Randomized Controlled TrialA randomised controlled trial of parecoxib, celecoxib and paracetamol as adjuncts to patient-controlled epidural analgesia after caesarean delivery.
The benefit of combining non-opioid analgesics with neuraxial opioids for analgesia after caesarean delivery has not been clearly established. Larger doses of paracetamol or cyclooxygenase-2 inhibitors have not been evaluated. A randomised, double blind, double-dummy, parallel group placebo-controlled clinical trial was conducted among women having elective caesarean delivery under spinal anaesthesia, followed by pethidine patient-controlled epidural analgesia. ⋯ There were no differences between groups for pethidine consumption, based on either intention-to-treat (median 365, 365, 405 and 360 mg in groups C, PC, PA and PCPA respectively, P=0.84) or per protocol analysis (17 major violations). Dynamic pain scores did not differ between groups but requirement for, and dose of, supplementary oral tramadol was least in group PCPA (incidence 23% versus 48%, 70% and 58% in groups C, PC and PA respectively, P=0.004). The addition of regular paracetamol, cyclooxygenase-2 inhibitors or both to pethidine patient-controlled epidural post-caesarean analgesia did not provide a pethidine dose-sparing effect during the first 24 hours.

ReviewPreventing cerebral oedema in acute liver failure: the case for quadruple-H therapy.
Severe cerebral oedema is a life-threatening complication of acute liver failure. Hyperammonaemia and cerebral hyperaemia are major contributing factors. A multimodal approach, which incorporates hyperventilation, haemodiafiltration, hypernatraemia and hypothermia (quadruple-H therapy), may prevent or attenuate severe cerebral oedema. ⋯ The administration of concentrated saline increases serum tonicity and further reduces cerebral swelling. In addition, the pathologically increased cerebral blood-flow is further attenuated by therapeutic hypothermia. The combination of all four treatments in a multimodal approach may be a safe and effective means of attenuating or treating the cerebral oedema of acute liver failure and preventing death from neurological complications.

Randomized Controlled TrialParecoxib and paracetamol for pain relief following minor day-stay gynaecological surgery.
Paracetamol and non-steroidal anti-inflammatory drugs are often administered for postoperative analgesia. Dilatation and curettage, with or without hysteroscopy, is a common day-stay procedure that is associated with pain that is partly mediated by prostaglandins. This study aimed to investigate the analgesic efficacy of adjunctive paracetamol and parecoxib in this setting. ⋯ There were no significant differences in patient satisfaction or recovery. We conclude that paracetamol or parecoxib does not produce a clinically important reduction in pain in this setting. Women having uterine curettage and receiving intravenous fentanyl do not appear to benefit from administration of these non-opioid analgesics.

Implications for Australian anaesthetists and proceduralists of a recent court decision regarding informed consent and patient positioning.
This article discusses the medicolegal implications of a recent judgment in relation to a patient who suffered significant morbidity as a result of patient positioning during an operative procedure. The patient developed an unexpected serious complication following surgery, in the context of a preoperative consent that did not cover every potential complication or contingency. ⋯ This finding is well aligned to current clinical practice and at the same time does not abrogate the practitioner's duty to provide a comprehensive list of possible complications during the consent process for any proceduralist. In the context of a procedure requiring anaesthesia, the importance of communication and understanding between the anaesthetist and proceduralist as to which aspects of the consent process are undertaken by whom, and to ensure the process is done comprehensively, is of great importance and is indirectly highlighted by this recent judgment.
