Randomized Controlled Trial Comparative Study Clinical TrialPre-emptive effect of pre-incisional versus post-incisional infiltration of local anaesthesia on children undergoing hernioplasty.
Although promising in experimental studies of post-traumatic pain, the concept of pre-emptive analgesia is still controversial in a clinical setting. Thus, we wanted to compare the clinical efficacy of wound infiltration with local anaesthesia before surgery with wound infiltration after hernioplasty in children. ⋯ Perioperative infiltration with a local anaesthetic in children undergoing hernioplasty results in a smooth recovery with little need for opioids postoperatively. Apart from a lower anaesthetic requirement and a reduced postoperative pain level after 30 min in the pre-incisional bupivacaine group, there was no difference between infiltration before (pre-emptive) or after surgery.

Randomized Controlled Trial Clinical TrialAnalgesic effect of intraarticular morphine. A controlled, randomised and double-blind study.
Opioids produce antinociceptive effect by acting on receptors on peripheral nerves. The clinical relevance of this effect is still debated. The aim of the study was to compare the analgesic effect of morphine intraarticularly with the intramuscular route of administration after knee surgery. ⋯ The clinical analgesic effect of 5 mg morphine given intraarticularly is equal to 5 mg morphine given intramuscularly. The occurrence of villous synovitis seems to be of no clinical importance concerning the local effect of morphine.

Randomized Controlled Trial Clinical TrialThe effects of warming intravenous fluids on intraoperative hypothermia and postoperative shivering during prolonged abdominal surgery.
The infusion of several liters of crystalloid solution at room temperature may significantly contribute to intraoperative hypothermia because warming fluid to core temperature requires body heat. The aim of this study was to evaluate the effect of delivering warmed intravenous (IV) fluid to the patient on preventing intraoperative hypothermia. ⋯ In conclusion, infusion of warmed fluids, combined with skin-surface warming, helps to prevent hypothermia and reduces the incidence of postoperative shivering.
