Harperwoman was given several litres of fluid over a few hours,after which she developed severe chest pain and breathlessness,followed by frank pulmonary oedema and cardiacarrest. Another woman with high urea and creatinine andminimal urinary output despite two litres of fluid hadacute renal failure, but dehydration was diagnosed andsome additional litres of fluid over a few hours were prescribedinappropriately.Fluid balance is difficult <strong>to</strong> manage in septic shock. Septicshock may be defined as sepsis with hypotension whichis refrac<strong>to</strong>ry <strong>to</strong> fluid resuscitation. Hypotension is the resul<strong>to</strong>f loss of vasomo<strong>to</strong>r <strong>to</strong>ne causing arterial vasodilationalong with reduced cardiac output because of myocardialdepression, and there is also increased vascular permeabilityso that fluid leaks in<strong>to</strong> the extravascular compartment.Renal failure and use of oxy<strong>to</strong>cic drugs, which are antidiuretic,may compound the problem.Careful moni<strong>to</strong>ring of fluid balance is important. Clear,accurate records of all intravenous fluids given and urinaryoutput and any other fluid loss should be kept and chartedso that significant fluid deficit or excessive input can beeasily detected. Although aggressive fluid resuscitation isusually needed in severe sepsis and septic shock, thisshould always be under close moni<strong>to</strong>ring <strong>to</strong> evaluate thewoman’s response and avoid the development of pulmonaryoedema. 8 Vasopressors are usually required, and acentral venous pressure line may help <strong>to</strong> moni<strong>to</strong>r fluid balance.It is essential <strong>to</strong> involve the anaesthetic and criticalcareteams as early as possible in the care of such criticallyill women.Fluid balance in septic shock:learning pointsSeptic shock is sepsis with arterial hypotension that isrefrac<strong>to</strong>ry <strong>to</strong> fluid resuscitation.Fluid overload may lead <strong>to</strong> fatal pulmonary or cerebraloedema.Clear, accurate documentation and careful moni<strong>to</strong>ringof fluid balance is essential <strong>to</strong> avoid fluid overload inwomen who are unwell, especially when hourly urineoutput is low or renal function is impaired. The adviceof an anaesthetist and the critical care team should besought at an early stage.Sustained increase in respira<strong>to</strong>ry rate >20 breaths/minuteor low oxygen saturation despite high-flow oxygen aresignificant clinical findings that should prompt urgentexamination of the lung fields, lower limbs (for evidenceof deep vein thrombosis), arterial blood gas measurement,electrocardiogram, and consideration of chest X-ray and ventilation perfusion scan <strong>to</strong> rule out problemssuch as pulmonary oedema, embolus or infection.Removing the source of sepsisThe focus of infection should be identified as a priority,and, if surgery is necessary <strong>to</strong> remove the source of sepsis,it should be carried out earlier rather than later or as alast resort—whether laparo<strong>to</strong>my, evacuation of suspectedretained products of conception, or other procedure. Laparo<strong>to</strong>mieswere performed in several of the women withthe aim of identifying and removing the septic focus.Deciding whether <strong>to</strong> operate is difficult, particularly whena woman is already critically ill and there is a high risk ofmassive haemorrhage. It is important <strong>to</strong> stabilise the<strong>maternal</strong> condition as far as possible before giving anaesthesia,which may further destabilise the woman, and <strong>to</strong>ensure that adequate cross-matched blood and bloodproducts are readily available. When there is massive a<strong>to</strong>nicuterine haemorrhage, conservative measures such ascarboprost may be tried, but if response <strong>to</strong> initial doses ispoor, hysterec<strong>to</strong>my undertaken sooner rather than latermay be lifesaving. In most cases laparo<strong>to</strong>my was undertakenas a last resort, but in a few cases earlier interventionmay have changed the outcome. In one womanwhose uterus was clearly infected, hysterec<strong>to</strong>my was consideredbut decided against because she was critically illand surgery was considered <strong>to</strong>o risky; in retrospect itmight have offered a chance of survival.Operative intervention: learningpointsPersistent or swinging pyrexia and failure <strong>to</strong> respond <strong>to</strong>treatment may be the result of a persistent deep-seatedfocus of infection. Every effort should be made <strong>to</strong> locateand deal with the source of sepsis. Computed <strong>to</strong>mographyis a useful investigation but may not show soft tissuechanges clearly, so magnetic resonance imagingshould also be considered.If the uterus is the primary focus of postnatal infection,retained products should be excluded by ultrasoundscan and exploration of the uterine cavity considered ifthere is still doubt. Hysterec<strong>to</strong>my should be consideredat an early stage, even if the woman is critically ill,because it may be lifesaving.Before surgery, adequate cross-matched blood andblood products should be requested and the <strong>maternal</strong>condition should be stabilised as far as possible.Carboprost can be effective in the treatment of uterinea<strong>to</strong>ny but has serious adverse effects, including airwayconstriction and pulmonary oedema, so it should beused with great caution—especially if multiple doses arerequired. If there is no response <strong>to</strong> one or two doses,other methods of dealing with the situation, such ashysterec<strong>to</strong>my, must be considered.94 ª <strong>2011</strong> Centre for Maternal and Child Enquiries (CMACE), BJOG 118 (Suppl. 1), 1–203
Chapter 7: SepsisLaparo<strong>to</strong>my for suspected intra-abdominal infectionshould involve a general surgeon as well as an obstetrician,as surgeons have a fundamentally differentapproach <strong>to</strong> laparo<strong>to</strong>my and are more likely <strong>to</strong> <strong>make</strong> amid-line incision <strong>to</strong> allow full exploration of theabdominal cavity.Leadership and continuity of careWhen managing complex cases, it must be clear who is incharge of the woman’s care. This is particularly importantwhen an unwell pregnant woman presents <strong>to</strong> the EmergencyDepartment rather than the Maternity or GynaecologyDepartments, as there may be a tendency for everyone <strong>to</strong>assume that someone else is looking after her. In one case,although several doc<strong>to</strong>rs were involved in one woman’s earlycare, no consultant <strong>to</strong>ok overall responsibility, nor were antibioticsgiven, until she collapsed over 24 hours after admission,by which time the outcome was inevitable.Documentation and communicationMany different medical, nursing and midwifery staff maybe involved in the ongoing care of an unwell woman andeach may see her only once or twice. This <strong>make</strong>s the assessmen<strong>to</strong>f any changes in the woman’s condition very difficult.In some of the cases already discussed in this Chapter,the mother’s vital signs were either not recorded routinelyor their significance was not recognised. One of the ‘Topten’ recommendations in the last Report was for routineuse of a MEOWS chart <strong>to</strong> help in the more timely recognition,treatment and referral of women who have, or aredeveloping, a critical illness. A MEOWS chart is the easiestway <strong>to</strong> see trends in a woman’s condition and <strong>to</strong> alert staff<strong>to</strong> take appropriate action or call for help. For example:A woman in late pregnancy with a short his<strong>to</strong>ry of sorethroat, vomiting, diarrhoea and abdominal pain was tachycardicand hypotensive on admission. Sepsis was not diagnosedfor some hours.The severity of her condition might have been recognisedsooner if a MEOWS chart had been used, and earlier antibiotictreatment and multidisciplinary care in a high-dependencysetting might possibly have changed the outcome.Involvement of other staffAnaesthetic and critical-care staff play a vital part in theeffective management of sepsis and should be involved asearly as possible, particularly when there is circula<strong>to</strong>ry orrespira<strong>to</strong>ry failure. For six women, also discussed in Chapter8, there were significant delays in seeking help from anaesthetistsand critical-care specialists.In some cases, hospital departments seemed <strong>to</strong> be verybusy and staff were said <strong>to</strong> be overstretched, although it isnot clear if this was directly related <strong>to</strong> the outcome. Forexample, it <strong>to</strong>ok several hours for two ill women <strong>to</strong> be seenby a doc<strong>to</strong>r or obstetric team because they were said <strong>to</strong> bevery busy elsewhere. The husband of another very sickwoman complained about the wait in a busy maternity unitand was <strong>to</strong>ld that, as his wife was not seriously ill, the doc<strong>to</strong>rwas seeing other more urgent patients. She died shortly after.Apart from the women whose rapidly fulminating diseasemeant they died at home or shortly after admission inthe Emergency Department, most other women died incritical care or operating theatres, reflecting the gravity oftheir condition. However, a few died in hospital wards,illustrating that seriously ill women were sometimes managedin inappropriate settings with inexperienced stafflooking after them.Sometimes there was a lack of co-ordinated care and littleor no support from senior staff when requested, butthere were also many examples of excellent teamwork. Forexample, as the assessors noted:This woman was extremely ill on admission and could nothave been saved. Her care could not have been better.Everyone, including consultants, was called and attendedextremely promptly, even though it was the middle of thenight. The teamwork was excellent.For most cases, there was a critical review by the Trust,and some also invited external assessment. Some of thesereviews were excellent, but, as with other cases counted inother chapters, many focused on irrelevant issues and failed<strong>to</strong> identify major elements of substandard care or <strong>to</strong> learnanything from the event.
