It will cover principally the UK response to the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), although it will also compare and contrast other diseases and reference more general principles of major incident planning. Areas that individual surgeons and departments can, and should, influence are discussed.

The first required anaesthesia during the second trimester for a minor surgical procedure. The second woman was admitted to the Intensive Care Unit in the first trimester and was ventilated for 18 weeks. Both babies were carried to term and delivered by Caesarean section. A review of the management of Guillain Barré syndrome in pregnancy discusses anaesthetic management, intensive care and the use of plasmapheresis and γ‐globulins. The care of pregnant women recovered from Guillain Barré syndrome is also discussed.

His condition was stabilised prior to transfer to the UK using continuous venovenous haemofiltration. This is the first deployed use of renal replacement therapy by UK forces for several decades, and raises questions regarding the provision of this high level capability in the deployed setting.

If persistent, the resultant hypoxemia is associated with increased ventilator days, prolonged length of stay (intensive care and hospital) and increased 28-day mortality. Ventilation strategies for the management of hypoxemia in acute lung injury include moderate to high levels of PEEP (positive and expiratory pressure) and prone ventilation (PV). Such strategies have theoretical adverse effects on graft perfusion. Evidence does however exist to demonstrate that maintenance of cardiac output and correct positioning of the prone patient to allow abdominal excursion can negate the deleterious effects of PEEP and PV. A liver transplant recipient became profoundly hypoxemic on our intensive care unit following the onset of noncardiogenic pulmonary edema. A risk-benefit assessment performed at the time deemed that the potential adverse effects of PEEP and PV were outweighed by the life-threatening nature of hypoxemia. The patient's condition improved following prone positioning and application of PEEP (10-15 cm H(2)O). We conclude that such ventilation strategies are appropriate in hypoxemic liver transplant recipients if an appropriate risk-benefit assessment is performed.

We have recently conducted a single-centre randomised study of GDT, during which 179 unselected patients having elective colorectal surgery received standard fluid therapy with or without supplementary colloid boluses guided by ODM [7]. Deltex, manufacturers of the CardioQ ODM, provided educational support but remained otherwise independent. Control patients typically received 2.7–4.5 l isotonic crystalloid during the procedure. We found that GDT had no impact on any important clinical endpoints [7]. A unique feature of this trial was that all patients had their aerobic fitness quantified by a pre-operative cardiopulmonary exercise test, such that they could be broadly classified as ‘fit’ or ‘unfit’ in terms of their functional capacity to deliver oxygen to tissues. Roughly, one third were classed as unfit. Some interesting trends became apparent: GDT appeared to hamper the recovery of fit patients, possibly due to fluid overload, such that they took a median of two days longer to reach discharge readiness, whilst there was no such detrimental effect in unfit patients. Moreover, clinical outcomes in our control group were comparable to those of the intervention group in earlier ODM ⁄ GDT trials. Ours is also a small trial, similarly susceptible to confounders: here there was an imbalance in the proportion of colonic versus rectal procedures that favoured the control group. Intra-operative fluid management for major colorectal surgery is a matter of ensuring euvolaemia such that tissue oxygen demand is met by means of adequate organ perfusion throughout the peri-operative period. In our view, and more compellingly in our study, for the majority of our elective patients this can be adequately judged without recourse to expensive additional monitoring.

We assessed the effect of esophageal Doppler guided cardiovascular optimization in patients undergoing radical cystectomy. We conducted a prospective, randomized, double-blind controlled trial at a United Kingdom teaching hospital between 2006 and 2009. A total of 66 patients were randomized to a control arm (34) and an intervention arm (32). The control group received standard intraoperative fluids. The intervention group received (additional) Doppler guided fluid. Primary outcomes were markers of gastrointestinal morbidity such as ileus, flatus and bowel opening. Secondary outcomes were postoperative nausea and vomiting, wound infection and operative intravenous fluid volumes (total and hourly). There were significant reductions in the control and intervention arms in the incidence of ileus (18 vs 7, p <0.001), flatus (5.36 vs 3.55 days, p <0.01) and bowel opening (9.79 vs 6.53 days, p = 0.02), respectively. Nausea and vomiting were significantly reduced in the study group at 24 and 48 hours postoperatively (11 vs 3, p…
