Post-operative analgesic consumption is often used as a surrogate measure for pain; analyses of mean data assume a Gaussian distribution and use parametric statistics to assess statistical differences, often in small samples. We used a large individual patient dataset to examine the distribution of analgesic consumption, the validity of such analyses and alternative dichotomous outcomes. ⋯ Because of a highly skewed distribution, post-operative analgesic consumption is an uncertain method of measuring analgesic efficacy of an intervention designed to limit pain during and after surgery.

Randomized Controlled Trial
Acupressure at acupoint P6 for prevention of postoperative nausea and vomiting: a randomised clinical trial.
Postoperative nausea and vomiting causes discomfort in many patients despite both antiemetic prophylactics and improved anaesthetic techniques. Stimulation of acupoint P6 is described as an alternative method for prophylaxis of postoperative nausea and vomiting.In a randomised, double-blinded study, we aimed to investigate the effect of P6 acupoint stimulation on the incidence of postoperative nausea and vomiting within 24 h postoperatively with an acupressure wristband: Vital-Band. ⋯ We did not find the Vital-Band effective in preventing either nausea or vomiting after operation in women undergoing breast surgery.

Randomized Controlled Trial
Transcutaneous electrical nerve stimulation on ST36 and SP6 acupoints prevents hyperglycaemic response during anaesthesia: a randomised controlled trial.
Hyperglycaemia is a common result of stress signals caused by pain and surgical procedure. Volatile anaesthetics also directly manipulate glucose homeostasis by affecting pancreatic insulin release and induce hyperglycaemia without surgical stress. We determined the preoperative application of transcutaneous electrical nerve stimulation (TENS) to the Chinese acupoints ST36 (Zusanli) and SP6 (Sanyinjiao) as a complementary therapy for controlling plasma glucose and improving insulin resistance during anaesthesia. ⋯ We found TENS at bilateral ST36 and SP6 acupoints to be an alternative means of managing the plasma glucose level and improving insulin resistance perioperatively.

Randomized Controlled Trial
Intraocular pressure and haemodynamic responses to insertion of the i-gel, laryngeal mask airway or endotracheal tube.
We hypothesised that the effects of insertion of an i-gel supraglottic airway management device on intraocular pressure (IOP) and haemodynamic variables would be milder than those associated with insertion of a laryngeal mask airway (LMA) or an endotracheal tube. ⋯ Insertion of the i-gel device provides better stability of IOP and the haemodynamic system compared with insertion of an endotracheal tube or LMA in patients undergoing elective non-ophthalmic surgery.
