Two died in the early postnatal period and the remainder died between two and eleven months after giving birth antibiotics zinc deficiency purchase trimethoprim 960 mg. Five women died in fres virus protection for ipad 480 mg trimethoprim visa, one following a fall and eleven as the result of road trafc accidents oral antibiotics for acne while pregnant buy generic trimethoprim 960 mg on line. All the women who were pregnant at the time of their road trafc accident were wearing seatbelts ebv past infection order trimethoprim 480mg, although one woman who died postnatally was unrestrained. A second woman with a his to ry of substance abuse and late booking died in a road trafc acci dent while her baby was in the special care baby unit. It was unclear whether any suicidal intent was involved in either of these women’s deaths. No to xicology was carried out at the frst woman’s post-mortem examination so it is unclear whether she was under the infuence of drugs or alcohol, or had therapeutic levels of medication. The possibility of suicide does not appear to have been considered in either instance, yet both had multiple adversities and evidence of disengagement with care. Additionally one of these women died around the time of a case conference; this may have increased her vulnerability. In women facing multiple adversity, changes in frequency or nature of presentations may refect worsening mental state or the emergence of new complications (such as alcohol or substance misuse or interpersonal violence), and should prompt renewed attempts at engagement, diagnosis and care co-ordination. Disengagement from care should be regarded as a potential indica to r of worsening mental state. All profes sionals involved in the woman’s care should be informed of non-attendances and assertive follow-up arranged where there is already concern regarding mental state or prior evidence of risk. It is unclear how much support was given to this new mother and baby and whether extra input from external sources could have prevented her death. The community midwife correctly identifed that she was exceptionally vulnerable and referred her for additional support with the family nurse part nership, unfortunately the referral was refused as her problems were considered to o complex. There seems to have been little recognition that this mother was herself under 18, and that safeguarding issues applied equally to both her and her baby. The fact that she was considered to o complex for help from the family nurse partnership highlights the ongoing need for guidance about how these woman can be appropriately cared for. There is a need for practical national guidance for the management of women with multiple morbidities and social fac to rs prior to pregnancy, and during and after pregnancy (Knight et al. Paramedics transported her rapidly to the Emergency Department where a number of consult ants were already in attendance: anaesthetists, accident and emergency, intensive care and gynaecology. She had intraosseous access already inserted and central venous access was established very soon after arrival. However, despite protracted resuscitation her bleeding could not be controlled and she died. At all stages of her care this woman was managed appropriately and rapidly and with senior involvement but the severity of her injuries led to her ultimate death. There were several other instances of exemplary resuscitation attempts which were ultimately unsuccessful. However, in a few instances some of the key elements of resuscita tion of pregnant women were not considered. A woman involved in a road trafc accident during the third trimester of pregnancy underwent resuscitation at the scene. On arrival at the emer gency department a rapid perimortem caesarean section was carried out prior to further surgery but she did not survive her multiple injuries. Her precise cause of death is not clear but the hypovolaemia caused by her haemothorax would have had a greater efect if her inferior vena caval compression was unrelieved by uterine displacement. From 20 weeks of gestation onwards, the pressure of the gravid uterus must be relieved from the inferior vena cava and aorta. A left lateral tilt of 15° on a frm surface will relieve aor to caval compression in the majority of pregnant women and still allow efective chest compressions to be performed. A left lateral tilt of 15° can be achieved on an operating table using a Cardif wedge or by having someone kneel on the right side of the woman with their knees under the woman’s thorax. In the absence of a spinal board, manual displacement of the uterus should be used. Using soft surfaces such as a bed or objects such as pillows or blankets is not nearly as efective and compromises efective chest compressions, but is better than leaving the woman supine. In one instance the perimortem caesarean section was not carried out at the request of her family, although the woman was still unstable following return of spontaneous circulation. Caesarean section and delivery of fetus and placenta will still aid maternal resuscitation in this situation, and it must be remembered that perimortem caesarean section is a resuscitative procedure to be performed primarily in the interests of maternal, not fetal, survival (Royal College of Obstetricians and Gynaecologists 2011, Chu et al. In most instances this was because a local review had not taken place, or had not involved the maternity services where the majority of her care was delivered, even when women had died during or shortly after pregnancy. As this chapter illustrates, messages for care are still evident when women have died during or after pregnancy from accidental causes, and local review should not be neglected. Whilst this may be appropriate, the reason for this choice of investigation should be docu mented. Assessors were unclear whether these decisions were made for clinical or family reasons. Nevertheless, women who died in fres are possibly over-represented in the pregnant and postpartum population, emphasising the importance of preventive measures such as smoke alarms in households with young children. Review of these women’s deaths showed areas where care could be improved, particularly in relation to resuscitation, focussing on the use of lateral tilt and perimortem caesarean section to aid resuscitation. It was not felt that these improvements would have made a diference to the women’s outcomes. Development of a national, evidence-based, early warning scoring system for pregnant and postpartum women should be a priority. Any disputes and disagreements amongst members of the clinical team should be settled and information from post-mortem examinations and inquests should be considered to ensure that team members have a shared understanding of the lessons to be learned. Local inves tigations and reviews of maternal death should not be confned to a timeline of events and a clinical narrative. The strength or weakness of multi-disciplinary team working should merit specifc comment. Pregnant or recently pregnant women should have access at all times to a healthcare professional who has enhanced maternal care competencies. The route of escalation to critical care services should be clearly defned, and include multidisciplinary discussion. Critical care outreach or an equivalent service should be available to ill women, and provide support and education to healthcare professionals delivering enhanced maternal care. In the event of collapse in the community in pregnancy, if time critical features are present, transfer to the nearest appropriate destination, with a pre-alert stating the emergency. If signifcant shock or compromise, consider the emergency department in the frst instance. Where sepsis is present the source should actively be sought with appropriate imaging and consideration given to whether surgical or radiological-guided drainage is required. This chapter examines the lessons that can be learnt from 41 women who died and who had contact with critical care services at the end of their lives. The case records have been scrutinised by assessors with expertise in critical care medicine who had no involvement in the treatment and can provide an independent review of the care the women received. It contains recommendation relevant to intensive care medicine specialists, emergency physicians, obstetricians, midwives, nurses and primary responders (para medics and ambulance technicians). Issues that have been highlighted in previous reports recurred in this series of maternal deaths and this chapter should be read alongside previous recommendations. The importance of early recognition of the critically ill mother and prompt involvement of senior clinicians needs to be repeated as does the need to re-evaluate how we work in multidisciplinary teams. The chapter begins with recommendations about maternal collapse/cardiac arrest both in the community and in the hospital setting. It goes on to comment on aspects of clinical assessment and critical care management of the sick mother. Finally there are comments about the recording and audit of clinical data for this group of patients and advice on the investigation and discussions that should take place after a maternal death. Unsurprisingly, their causes of death mirror the overall causes of maternal death (Table 8.

Loss of the Achilles refiex is increasingly prevalent with normal healthy ageing antibiotic vantin purchase trimethoprim 480 mg mastercard, beyond the age of 60 years infection taste in mouth buy discount trimethoprim 480mg, although more than 65% of patients retain the ankle jerks antibiotics jaw pain buy cheap trimethoprim 480 mg line. This may be ophthalmological or neurological in origin antibiotics making me tired cheap 480mg trimethoprim, congenital or acquired; only in the latter case does the patient complain of impaired colour vision. Cerebral achroma to psia results from cortical damage (most usually infarction) to the inferior occipi to temporal area. Transient achroma to psia in the context of vertebrobasilar ischaemia has been reported. The differential diagnosis of achroma to psia encompasses colour agnosia, a loss of colour knowledge despite intact perception; and colour anomia, an inability to name colours despite intact perception. A brief to pographical overview of age-related signs includes • Cognitive function: Loss of processing speed, cognitive fiexibility, efficiency of working memory (sustained attention); Preservation of vocabulary, remotely learned information including semantic networks, and well-encoded new information. There does seem to be an age-related loss of distal sensory axons and of spinal cord ventral horn mo to r neurones accounting for sensory loss, loss of muscle bulk and strength, and refiex diminution. This may be tested by application to each half of the protruded to ngue the four fundamental tastes (sweet, sour, bitter, and salt). Ageusia as an isolated symp to m of neurological disease is extremely rare, but has been described with focal central nervous system lesions (infarct, tumour, demyelination) affecting the nucleus of the tractus solitarius (gusta to ry nucleus) and/or thalamus and with bilateral insular lesions. Lissauer (1890) originally conceived of two kinds of agnosia: • Apperceptive: In which there is a defect of complex (higher order) perceptual pro cesses. Moreover, the possibility that some agnosias are in fact higher-order perceptual deficits remains: examples include some types of visual and tactile recognition of form or shape. Other terms which might replace agnosia have been suggested, such as non-committal terms like ‘disorder of perception’ or ‘perceptual defect’, or as suggested by Hughlings Jackson ‘imperception’. With the passage of time, agnosic defects merge in to anterograde amnesia (failure to learn new information). Ana to mically, agnosias generally refiect dysfunction at the level of the association cortex, although they can on occasion result from thalamic pathol ogy.

Whether this is a perceptual deficit or a tactile agnosia (‘agraphognosia’) remains a subject of debate. Cross References Agnosia; Tactile agnosia Agraphia Agraphia or dysgraphia is a loss or disturbance of the ability to write or spell. From the linguistic viewpoint, two types of paragraphia may be distinguished as follows: Surface/lexical/semantic dysgraphia: misspelling of irregular words, producing phonologically plausible errors. Akathisia Akathisia is a feeling of inner restlessness, often associated with restless move ments of a continuous and often purposeless nature, such as rocking to and fro, repeatedly crossing and uncrossing the legs, standing up and sitting down, and pacing up and down (forced walking, tasikinesia). Treatment of akathisia by reduction or cessation of neuroleptic therapy may help, but may exacerbate coexistent psychosis. Neurophysiologically, akinesia is associated with loss of dopamine projec tions from the substantia nigra to the putamen. Cross References Akinetic mutism; Bradykinesia; Extinction; Frontal lobe syndromes; Hemiakinesia; Hypokinesia; Hypometria; Kinesis paradoxica; Neglect; Parkinsonism Akinetic Mutism Akinetic mutism is a ‘syndrome of negatives’, characterized by a lack of vol untary movement (akinesia), absence of speech (mutism), and lack of response to question and command, but with normal alertness and sleep–wake cycles (cf. Pathologically, akinetic mutism is associated with bilateral lesions of the ‘centromedial core’ of the brain interrupting reticular-cortical or limbic-cortical pathways but which spare corticospinal pathways; this may occur at any point from frontal lobes to brainstem. Pathology may be vascular, neoplastic, or structural (subacute communicating hydrocephalus), and evident on structural brain imaging. Stendhal’s aphasic spells: the first report of transient ischemic attacks followed by stroke. The word dyslexia, though in some ways equivalent, is often used to denote a range of disorders in people who fail to develop normal reading skills in childhood. Alexia may be categorized as: • Peripheral: A defect of perception or decoding the visual stimulus (written script); other language functions are often intact. Peripheral alexias include • Alexia without agraphia: Also known as pure alexia or pure word blindness. Pure alexia has been characterized by some authors as a limited form of associative visual agnosia or ventral simultanagnosia. Patients tend to be slower with text than single words as they cannot plan rightward reading saccades. The various forms of peripheral alexia may coexist; following a stroke, patients may present with global alexia which evolves to a pure alexia over the following weeks. Global alexia usually occurs when there is additional damage to the splenium or white matter above the occipital horn of the lateral ventricle. Hemianopic alexia is usually associated with infarction in the terri to ry of the posterior cerebral artery damaging geniculostriate fibres or area V1 itself, but can be caused by any lesion outside the occipital lobe that causes a macular splitting homonymous field defect. Central (linguistic) alexias include • Alexia with aphasia: Patients with aphasia often have coexistent difficulties with reading (reading aloud and/or comprehending written text) and writing (alexia with agraphia, such patients may have a complete or partial Gerstmann -16 Alexithymia A syndrome, the so-called third alexia of Benson). The reading prob lem parallels the language problem; thus in Broca’s aphasia reading is laboured with particular problems in reading function words (of, at) and verb infiections (-ing, -ed); in Wernicke’s aphasia numerous paraphasic errors are made. Alexithymia is a common finding in split-brain patients, perhaps resulting from disconnection of the hemispheres. Some authors have subsequently interpreted these as somes thetic migrainous auras whereas others challenge this on chronological grounds, finding no evidence in Dodgson’s diaries for the onset of migraine until after he had written the Alice books. An arm so affected may show apraxic difficulties in performing even the simplest tasks and may be described by the patient as uncooperative or ‘having a mind of its own’ (hence alternative names such as anarchic hand sign, le main etranger, and ‘Dr Strangelove syndrome’). Frontal type: shows features of environmental dependency, such as forced grasping and groping, and utilization behaviour. Functional imaging studies in corticobasal degeneration, along with the evi dence from focal vascular lesions, suggest that damage to and/or hypometabolism of the medial frontal cortex (Brodmann area 32) and the supplementary mo to r area (Brodmann area 6) is associated with alien limb phenomena. Slowly progressive aphasia in three patients: the problem of accompanying neuropsychological deficit. Alloacousia Alloacousia describes a form of audi to ry neglect seen in patients with unilateral spatial neglect, characterized by spontaneous ignoring of people addressing the patient from the contralesional side, failing to respond to questions, or answering as if the speaker were on the ipsilesional side. Cross Reference Neglect Alloaesthesia Alloaesthesia (allesthesia, alloesthesia) is the condition in which a sensory stim ulus given to one side of the body is perceived at the corresponding area on the other side of the body after a delay of about half a second. The trunk and proximal limbs are affected more often than the face or distal limbs. Visual alloaesthesia, the illusory transposition of an object seen in one visual field to the contralateral visual field, is also described, for example in ‘ to p of the basi lar’ syndrome or with occipital lobe tumours. Tactile alloaesthesia may be seen in the acute stage of right putaminal haemorrhage (but seldom in right thalamic haemorrhage) and occasionally with anterolateral spinal cord lesions. The mechanism of alloaesthesia is uncertain: some 20 Allodynia A consider it a disturbance within sensory pathways, others consider that it is a sensory response to neglect. There is overlap with alloaesthesia, originally used by Stewart (1894) to describe stimuli displaced to a different point on the same extremity. Various pathogenetic mechanisms are considered possible, including sensi tization (lower threshold, hyperexcitability) of peripheral cutaneous nociceptive fibres (in which neurotrophins may play a role); ephaptic transmission (‘cross talk’) between large and small (nociceptive) afferent fibres; and abnormal central processing. Cross References Hyperalgesia; Hyperpathia -21 A Allographia Allographia this term has been used to describe a peripheral agraphia syndrome character ized by problems spelling both words and non-words, with case change errors such that upper and lower case letters are mixed when writing, with upper and lower case versions of the same letter sometimes superimposed on one another. Altitudinal field defects 22 Amblyopia A are characteristic of (but not exclusive to ) disease in the distribution of the cen tral retinal artery. This may result from: • strabismus; • uncorrected refractive error; • stimulus deprivation. Amblyopia may not become apparent until adulthood, when the patient sud denly becomes aware of unilateral poor vision. The finding of a latent strabismus (heterophoria) may be a clue to the fact that such visual loss is long-standing. Retrograde amnesia may show a temporal gradi ent, with distant events being better recalled than more recent ones, relating to the duration of anterograde amnesia. In a pure amnesic syndrome, intelligence and attention are normal and skill acquisition (procedural memory) is preserved. The neuroana to mical substrate of episodic memory is a distributed system in the medial temporal lobe and diencephalon surrounding the third ventricle (the circuit of Papez) comprising the en to rhinal area of the parahippocam pal gyrus, perforant and alvear pathways, hippocampus, fimbria and fornix, mammillary bodies, mammillothalamic tract, anterior thalamic nuclei, inter nal capsule, cingulate gyrus, and cingulum. Korsakoff ’s syndrome), which causes difficulty retrieving previously acquired memories (extensive retrograde amnesia) with diminished insight and a tendency to confabulation, has been suggested, but overlap may occur. Functional or psychogenic amnesia may involve failure to recall basic au to biographical details such as name and address. Clearly a premorbid apprecia tion of music is a sine qua non for the diagnosis (particularly of the former), and most reported cases of amusia have occurred in trained musicians. Isolated amusia has been reported in the context of focal cerebral atrophy affecting the non dominant temporal lobe.

Three further articles were studied which showed some relevance to the subject in question. This paper did, however, explore fast-track surgery with generally favourable results. The next paper, though descriptive in nature, to ok an interesting look in to the introduction of the enhanced recovery system to a gynaecology ward and the impact on ward nursing practices. This demonstrated that the expected gains of implementing an enhanced recovery system may be achieved without compromising the workload or work environment of ward nursing staff. The last article was an examination of patient and staff experiences of fast-track hysterec to my. Conclusions from the authors included recommendations that, in the future, staff must be fully informed regarding the system and that a new unit be set up dedicated to the recovery programme. Two reviews from the Cochrane database of Systematic Reviews displayed some relevance to our discussion and their contents will be discussed forthwith. No significant differences were found between the two in most parameters including pos to perative ileus, vomiting and first passage of flatus and s to ol pos to peratively, although there was an associated increase in pos to perative nausea associated with early feeding. A possibility of shorter hospital stay in patients with early oral intake was raised in the review although this would require further research. It was concluded that early feeding after major abdominal gynaecologic surgery is safe but that the approach must be individualised. The other Cochrane review examined the subject of surgical approach to hysterec to my for benign gynaecological disease. It was found, predictably, that the different routes of hysterec to my each carried their own benefits and risks. In conclusion it was stated that vaginal hysterec to my would be preferable to abdominal hysterec to my where possible, and that laparoscopic hysterec to my may have advantages in cases where vaginal hysterec to my was not possible. The route of hysterec to my must, however, be decided on an individual basis after discussion between the patient and surgeon. Conclusion the Enhanced Recovery after Surgery programme was first introduced and is now commonly used in colorectal surgery. It is increasingly becoming a part of the surgical system in many hospitals in disciplines including gynaecology, urology and orthopaedics. In gynaecology some of the elements of the programme already constitute established practice in many hospitals, but the complete system requires a smooth flowing process from preoperative patient preparation to pos to perative measures, including engagement of patients and staff throughout. This, however, requires more widespread evidence of the type considered in this review to demonstrate the potential benefits of the enhanced recovery programme to patients and staff across the country.

Introduction Surgery is often physically and psychologically stressful and in the pos to perative period, many patients experience significant amounts of pain and discomfort. The International Association for the Study of Pain defines pain as “an unpleasant sensory and emotional experience associated with actual or potential damage, or described in terms of such damage”. Although acute pain and associated responses can be unpleasant and often debilitating, they serve important adaptive purposes. They identify and localize noxious stimuli, initiate withdrawal responses that limit tissue injury, inhibit mobility thereby enhancing wound healing1. Nevertheless, intense and prolonged pain transmission2, as well as analgesic undermedication, can increase surgical postsurgical / traumatic morbidity, delay recovery, and lead to development of chronic pain. Despite the obviously simple nature of surgical incision, however, perioperative and specifically pos to perative pain remain underevaluated and poorly treated. Recent surveys suggest that 80% of patients experience pain after surgery3, 11% having severe pain, and that pain delays recovery in 24% of patients undergoing ambula to ry surgery4. Pathophisiology of acute pain A number of theories have been formulated to explain noxious perception: the specificity theory by Descartes, the intensity theory by Sydenham, and recently the gate control theory by Melzack and Wall where they suggested that sensory fibers of differing specificity stimulate second-order spinal neurons fire at a different intensity. Woolf and coworkers have proposed a new theory to explain pain-processing, suggesting that primary and secondary hyperalgesia as well as qualitative differences among physiologic, inflamma to ry, and neuropathic pain reflect sensitization of both peripheral nocicep to rs and spinal neurons. Noxious perception is the result of several distinct processes that begin in the periphery, extended up the neuraxis, and terminate at supraspinal regions responsible for interpretation and reaction. Most brain imaging studies report an activation of the sensory and affective brain structures following a nociceptive stimulus, demonstrating that pain perception is a complex experience with emotion, cognitive fac to rs, and previous experience playing an important role in perceived pain. It can therefore be unders to od why the clinician should address pain from both the physical as well the emotional aspect. Injured tissues will release various substances, such as potassium, prostaglandins, histamine, of bradykinins that are pronociceptive, and will also evoke an immune response. Primary hyperalgesia, which follows the release of these fac to rs, may be measured as a lowered pain threshold in and around the lesion. The most important fibers in the transmission of nociceptive stimulus are the Afi and C fibers. The first ones will rapidly transmit a brief and acute pinprick-like sensation, perceived to be precisely located at the point of stimulation. Following this activity, C fibers will transmit their information with a relatively long delay (100 millisenconds to a second, depending on the stimulus location). Repeated recruitment of C-fibers following an injury will produce central sensitization by changing the respose properties of the membranes of secondary neurons. This will result in an increase of the firing rate, a phenomenon known as windup10. The high frequency recruitment of C fibers, either by increased repetitive stimuli or by a to nic stimulation11, will induce an increase of the perceived pain, even if the intensity of the stimulation remains constant. The spinal sensitization can persist for minutes, but can also be present for hours and even days12. This neuronal plasticity of the secondary neuron will result in a reduced threshold in the spinal cord, producing hyperalgesic and allodynic responses that may persist even after the healing of the injury. Considering the impact of sensitization, an aggressive and early treatment plan to reduce pain will help in preventing ongoing chronic pain6. After reviewing some of the above mentioned theories, we can conclude that pain is a dynamic phenomenon; all the nociceptive signals will be modulated at all levels from the periphery to the brain but we still have to take in to account genetic and environmental fac to rs that will influence the acute perception and the development of persistent pain. Understanding the neurophysiologic mechanisms involved in the development and maintenance of pain will help the clinician to devise a more effective treatment plan. Risk fac to rs for developing chronic pain Three fac to rs have been proposed to play a role in the chronicity of pain: personal predisposition, environmental fac to rs, and psychologic fac to rs. It is also well known that chronic pain syndromes more frequently affect women than men; the reason for this predisposition is probably multifac to rial, with sex hormones likely Pos to perative Pain Management After Hysterec to my – A Simple Approach 271 playing an important role. The age is also a fac to r in this sort of patients; literature suggests that in the 50s it begins a reduction in endogenous pain control which contributes to the higher prevalence of chronic pain in the older population. Expectations of pain, which has not previously been experienced, may confound pain memory, especially when anxiety levels are high. Hysterec to my procedure is a high-risk surgery in terms of psychological and environmental ambience for most of the patients where the surgical team must be aware of these fac to rs. Physiology and ana to my of pain in hysterec to my Uterine innervation stems from a variety of sources. Parasympathetic nerves stemming from S2 to S4 conglomerate in to the cervical ganglion of Frankenhauser. Sympathetic nerves, the predominant influence in uterine innervation, descend from T7-T8 to the internal iliac plexi bilaterally to meet their parasympathetic counterparts. Together these nerves innervate not only the uterus, but also the bladder and upper vagina.
