Randomized Controlled Trial Comparative Study Clinical TrialRegional anaesthesia for outpatient knee arthroscopy: a randomized clinical comparison of two different anaesthetic techniques.
The purpose of this prospective, randomized study was to evaluate the time required to perform anaesthesia, achieve surgical block and fulfil standardized discharge criteria in outpatients receiving knee arthroscopy with either spinal anaesthesia or combined sciatic-femoral nerve block. ⋯ In patients receiving elective outpatient knee arthroscopy, using a combined sciatic-femoral nerve block with 25 ml of mepivacaine 20 mg ml(-1) and a multiple injection technique results in a slightly longer preoperative time but provides similarly effective anaesthesia with no differences in home discharge times as compared to spinal anaesthesia with 8 mg hyperbaric bupivacaine.

Randomized Controlled Trial Comparative Study Clinical TrialDay-case laparoscopy: a comparison of prophylactic opioid, NSAID or local anesthesia for postoperative analgesia.
The study was aimed to evaluate the analgesic efficacy, postoperative comfort, recovery characteristics and side effects of three different analgesic agents administered prophylactically. ⋯ Tenoxicam 20 mg i.v. was found to be ineffective whereas bupivacaine was superior to other groups in reducing pain and analgesic requirements. Bupivacaine also increased time to first analgesics and obtained better recovery characteristics, underlining its value in prophylactic pain management compared to the other two agents.

Randomized Controlled Trial Comparative Study Clinical TrialNo difference between bupivacaine in 0.9% and 8% glucose for spinal anaesthesia in small children.
Baricity is one of the most important factors to influence the characteristics of distribution of the local anaesthetic and hence success and spread of the blockade. Bupivacaine is rendered hyperbaric by adding glucose. The effect of differing degrees of hyperbaricity remains to be evaluated. ⋯ These results demonstrate that bupivacaine in 0.9% glucose and in 8% glucose solutions are equally suitable for spinal anaesthesia in small children. Similar success rate, spread and duration of the sensory and motor block are achieved with both baricities of bupivacaine.

Randomized Controlled Trial Clinical TrialLocal anaesthesia for awake fibreoptic nasotracheal intubation.
Awake fibreoptic nasotracheal intubation (FNI) is performed in potentially difficult airways under local anaesthesia. This observer-blinded study was designed to evaluate the efficacy of upper airway anaesthesia produced by nebulized lignocaine against combined regional block (CRB) for awake FNI. ⋯ Both nebulization and CRB produced satisfactory anaesthesia of the upper airway, but CRB provided better patient comfort and haemodynamic stability.

Randomized Controlled Trial Clinical TrialThe effect of dopexamine on regional tissue oxygenation, systemic inflammation and amino acid exchange in major abdominal surgery.
Beta-adrenergic agents are frequently used to improve cardiac performance in surgical and intensive care patients. Beta-adrenergic agents have metabolic and anti-inflammatory effects in addition to their cardiovascular effects. Splanchnic metabolic activity increases in response to surgery and inflammation. Dopexamine is believed to favor blood flow distribution to the splanchnic region. ⋯ Dopexamine, when added to a preoperative stabilization protocol with fluids, did not augment the postoperative hemodynamic response, and had no effect on postoperative metabolic and inflammatory responses.
