Randomized Controlled Trial Clinical TrialIntrathecal morphine provides effective and safe analgesia in children after cardiac surgery.
The purpose of this prospective, randomized, blinded to observer study was to assess the analgesic effect and safety of intrathecal morphine (ITM) in post-operative pain control in children after heart surgery with a sternotomy incision. ⋯ An ITM dose of 20 micrograms/kg had a significant (P = 0.03) intravenous morphine-sparing effect after cardiac surgery. Effective analgesia was observed for 12 h after administration of intrathecal morphine.

Comparative StudyLocal anesthesia use for laparoscopic cholecystectomy.
This study aimed to investigate the effects and timing of local anesthesia during laparoscopic surgery in terms of postoperative pain, nausea, and the need for opioids and antiemetics. This prospective study was carried out on 142 patients who underwent laparoscopic cholecystectomy. Peroperative local anesthesia was not administered to 53 patients (group A). ⋯ The time delay to the first antiemetics was significantly shorter in group A than in group C. Applying local anesthesia to the skin, subcutis, fascia, and parietal peritoneum through trocar sites reduces the postoperative analgesic requirement and pain intensity. This approach is more effective when applied at the end of an operation than at the start.

Randomized Controlled Trial Comparative Study Clinical Trial
Pre-emptive analgesia using intravenous fentanyl plus low-dose ketamine for radical prostatectomy under general anesthesia does not produce short-term or long-term reductions in pain or analgesic use.
The aim of the study was to evaluate post-operative pain and analgesic use after pre-operative or post-incisional i.v. fentanyl plus low dose i.v. ketamine vs. a standard treatment receiving i.v. fentanyl but not ketamine. Men undergoing radical prostatectomy under general anesthesia were randomly assigned in a double-blinded manner to one of three groups. Patients received i.v. fentanyl before incision followed by an i.v. bolus dose (0.2 ml kg(-1)) and an i.v. infusion (0.0025 ml kg(-1)min(-1)) of 1 mg ml(-1) ketamine (group 1) or normal saline (groups 2 and 3). ⋯ Pain scores and von Frey pain thresholds did not differ significantly among groups. Two-week and 6-month follow-ups did not reveal significant group differences in pain incidence, intensity, disability or mental health. Pre-operative, low-dose administration of i.v. ketamine did not result in a clinically meaningful reduction in pain or morphine consumption when compared with post-incisional administration of ketamine or a saline control condition.

This study examines the evidence from published data concerning the adverse respiratory and haemodynamic effects of three analgesic techniques after major surgery; i.m. analgesia, patient-controlled analgesia (PCA), and epidural analgesia. ⋯ Assuming a mixture of analgesic techniques, Acute Pain Services should expect an incidence of respiratory depression, as defined by a low ventilatory frequency, of less than 1%, and an incidence of hypotension related to analgesic technique of less than 5%.

[Bilateral pleural block: analgesia and pulmonary functions in postoperative of median laparotomies.].
Notwithstanding pleural block having become almost an analgesic panacea, contradictory results have been published. This study aimed at observing analgesic and spirometric behavior of pulmonary function in the immediate postoperative period of 21 patients submitted to urgency median laparotomies under bilateral pleural block. ⋯ In our study, postoperative pain control with bilateral pleural block after urgency median laparotomies was null with saline. With bupivacaine, however, analgesia was not considered fully effective in all patients during movements on bed and deep breathing. Pleural block does not seem to have the same analgesic outcome for all patients.
