Randomized Controlled Trial Comparative Study Clinical TrialProspective randomized trial of pre-emptive analgesics following ambulatory inguinal hernia repair: intravenous ketorolac versus diclofenac suppository.
A pre-emptive non-steroidal anti-inflammatory drug is routinely given to patients undergoing ambulatory inguinal hernia repair. The present prospective randomized trial was undertaken to compare the efficacy of intravenous ketorolac and rectal diclofenac for ambulatory inguinal hernia repairs. ⋯ Diclofenac suppository 50 mg and intravenous ketorolac 30 mg provided equivalent postoperative analgesia following ambulatory inguinal hernia repair under general anaesthesia. Diclofenac suppository is an economical alternative to intravenous ketorolac. In the interests of cost containment rectal diclofenac could be considered the non-steroidal anti-inflammatory drug of choice for pre-emptive analgesia.

Randomized Controlled Trial Clinical TrialEffectiveness of intra-operative wound infiltration with long-acting local anaesthetic.
Postoperative pain relief is of importance to both patients and surgeons. One of the simpler techniques is infiltration of the surgical incision with long acting local anaesthetic. The literature is confusing, with numerous reports attesting to the value of this approach and a similar number disputing the demonstrable benefits. ⋯ Intraoperative wound infiltration with bupivacaine is widely employed as a method of minimizing postoperative pain. This study was unable to demonstrate a benefit of employing the technique in terms of a reduction in the patient's perception of pain. By having each patient act as their own control, we have avoided one of the major deficiencies of previous studies, namely, interpatient variability in assessment and perception of pain.

Randomized Controlled Trial Comparative Study Clinical TrialMetabolic and immunologic consequences of laparoscopy with helium or carbon dioxide insufflation: a randomized clinical study.
Previous studies using animal models have demonstrated that carbon dioxide (CO2) pneumoperitoneum during laparoscopy is associated with adverse physiological, metabolic, immunological and oncological effects, and many of these problems can be avoided by the use of helium insufflation. The present study was performed in patients to compare the effect of helium and CO2 insufflation on intraperitoneal markers of immunological and metabolic function. ⋯ The choice of insufflation gas can affect intraperitoneal macrophage function in the clinical setting, and possibly acid-base balance. The present study suggested no immunological advantages for the clinical use of helium as an insufflation gas. The outcomes of the present study, however, are different to those obtained from previous laboratory studies and further research is needed to confirm this outcome.
