Randomized Controlled TrialPostoperative vomiting reduction after laparoscopic cholecystectomy with single dose of dexamethasone.
The incidence of postoperative nausea and vomiting (PONV) is high after laparoscopic surgery. A number of drugs have been used for prevention; in some studies a single dexamethasone dose before induction of anaesthesia has been effective. ⋯ Although only a small number of patients were tested, we confirm the efficacy of dexamethasone therapy for reduction of PONV. We suggest routine use of a single dose of dexamethasone for the prevention of PONV in laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative StudyPrevention of pain on injection of propofol: a comparison of remifentanil with alfentanil in children.
Propofol has a high incidence of pain on injection, particularly when a vein on the back of hand is used. Administration of lidocaine, either before or mixed with propofol remains the most widely used method to attenuate this pain. The use of opioids such as alfentanil and fentanyl has been found to decrease pain induced by propofol injection. The purpose of this study was to evaluate the effects of different doses of remifentanil and alfentanil in minimizing the pain caused by propofol. ⋯ Pretreatment with intravenous remifentanil 0.5 microg kg(-1), alfentanil 15 microg kg(-1) and 20 microg kg(-1) were equally effective in reducing pain associated with propofol injection in children between the age group of 5-12 years.

Randomized Controlled TrialFluid challenge in patients submitted to spinal block.
The practice of routinely prehydrating patients by infusing a colloid solution for prevention of spinal anesthesia-induced hypotension has been challenged recently. The aim of the study was to evaluate the influence of a 15 mL/kg pre-emptive bolus of colloids (6% hydroxyhethyl starch) on heart rate (HR), mean arterial blood pressure (MAP), cardiac index (CI) in patients submitted to subarachnoid block with hyperbaric bupivacaine 0.5%, 0.2 mg/kg for orthopedic surgery of the lower limb. ⋯ Our data show that despite to fluid challenge, we could not prevent MAP decrease in Group A, even if it is more marked in Group B.

Randomized Controlled Trial Comparative StudyComparison between spinal anaesthesia and sciatic-femoral block for arthroscopic knee surgery.
We compared spinal anesthesia and sciatic-femoral block for arthroscopic knee surgery in terms of hemodynamic changes, intraoperative anesthesia, postoperative analgesia, postoperative motor block and bladder function, side effects, and patient satisfaction. ⋯ In conclusion the sciatic-femoral nerve block is a valid alternative to spinal anesthesia for arthroscopic knee surgery, leading to a faster discharging from the hospital.

Randomized Controlled Trial Comparative StudyOne-day surgery for acquired forefoot deformity: sciatic nerve blockade with mepivacaine vs mepivacaine+ropivacaine: a prospective, randomized study.
The aim of the study was to determine the doses of ropivacaine combined with mepivacaine for sciatic nerve blockade to enable the extension of analgesia without prolonged motor blockade, for the management of very painful operations in one-day surgery. ⋯ Adequate doses of ropivacaine added to mepivacaine for peripheral blockade produce and increase the duration of analgesia without influencing the criteria for discharge after Day Surgery.
