Randomized Controlled Trial Comparative StudyUltrasound-guided infragluteal sciatic nerve block: a comparison between four different techniques.
Ultrasound guided sciatic block can be performed by different techniques. We compared namely short or long axis views of the sciatic nerve with in-plane or out-of-plane needle insertion techniques for the infragluteal sciatic nerve block (ISNB). ⋯ The LI approach required less time to complete the infragluteal sciatic nerve block procedure and it was more comfortable for the patients in comparison to the SO, SI and LO approaches.

Randomized Controlled TrialHaemodynamic optimisation in lower limb arterial surgery: room for improvement?
Goal-directed therapy has been proposed to improve outcome in high-risk surgery patients. The aim of this study was to investigate whether individualised goal-directed therapy targeting stroke volume and oxygen delivery could reduce the number of patients with post-operative complications and shorten hospital length of stay after open elective lower limb arterial surgery. ⋯ Perioperative individualised goal-directed therapy may reduce post-operative complications in open elective lower limb arterial surgery.

Randomized Controlled TrialDosage finding for low-dose spinal anaesthesia using hyperbaric prilocaine in patients undergoing perianal outpatient surgery.
Hyperbaric prilocaine 20 mg/ml may be preferable for perianal outpatient surgery. The aim of this prospective, single-centre, randomised, single-blinded, controlled clinical trial was to determine the optimal dosage of hyperbaric prilocaine 20 mg/ml for a spinal anaesthesia (SPA) in patients undergoing perianal outpatient surgery. ⋯ Hyperbaric prilocaine 20 mg/ml can be applied in dosages of 10, 20 and 30 mg for SPA in perianal surgery. Because of sufficient analgesia, missing motor block and shorter recovery times, 10 mg of hyperbaric prilocaine 20 mg/ml can be recommended for perianal outpatient surgery.

Randomized Controlled TrialOptimising stroke volume and oxygen delivery in abdominal aortic surgery: a randomised controlled trial.
Post-operative complications after open elective abdominal aortic surgery are common, and individualised goal-directed therapy may improve outcome in high-risk surgery. We hypothesised that individualised goal-directed therapy, targeting stroke volume and oxygen delivery, can reduce complications and minimise length of stay in intensive care unit and hospital following open elective abdominal aortic surgery. ⋯ Perioperative individualised goal-directed therapy targeting stroke volume and oxygen delivery did not affect post-operative complications, intensive care unit or hospital length of stay in open elective abdominal aortic surgery.

Randomized Controlled TrialHigh thoracic epidural analgesia decreases stress hyperglycemia and insulin need in cardiac surgery patients.
Assuming that high thoracic epidural analgesia (HTEA) with the sympathetic block might decrease postoperative blood glucose (BG) level and reduce the need of insulin, the aim was to evaluate the effect of HTEA on the BG level and insulin requirement in patients undergoing cardiac surgery. ⋯ HTEA preserves glucose metabolism better and leads to a lesser degree of 'stress hyperglycaemia' in cardiac surgery patients.
