Randomized Controlled Trial Comparative Study Clinical Trial
Managing pain during mediastinal chest tube removal.
To compare four analgesic regimens used in preparing patients for chest tube removal. ⋯ Blind ratings of subjects' descriptions of sensations suggest subfascial lidocaine may be useful in reducing discomfort during chest tube removal.

Randomized Controlled Trial Comparative Study Clinical TrialThoracic epidural analgesia compared with patient controlled intravenous morphine after upper abdominal surgery.
Twenty-one ASA I or II patients undergoing upper abdominal surgery were studied for 24 hours after operation. They were entered into a prospective, randomised study of patient-controlled intravenous morphine compared with continuous thoracic epidural fentanyl combined with 0.2% bupivacaine. ⋯ There was a reduced incidence of emetic symptoms in the epidural group (P < 0.05) but the incidence of other minor side effects did not differ significantly. Thoracic epidural fentanyl/bupivacaine results in significantly better analgesia than patient-controlled intravenous morphine.

Randomized Controlled Trial Clinical TrialThe effect of low-dose bupivacaine on postoperative epidural fentanyl analgesia and thrombelastography.
We performed a prospective, randomized, double-blind study to determine the effect of bupivacaine on postoperative epidural fentanyl analgesia and thrombelastography in 120 patients who underwent extensive gastrointestinal or genitourinary surgery. The patients were randomized into four groups, 30 patients per group: Group I = epidural fentanyl (EF), 10 micrograms/mL in saline; Group II = EF with 0.1% bupivacaine; Group III = EF with 0.15% bupivacaine; and Group IV = EF with 0.2% bupivacaine. Pain relief was evaluated by a visual analog scale (VAS), both at rest and during coughing, and by a visual rating scale (VRS). ⋯ The VAS, VRS, sedation scores, changes in postoperative FVCs, and the incidence of side effects were not statistically different among the four groups. The 24-h total volumes of infusion in the four groups (146 +/- 40 mL, 140 +/- 38 mL, 142 +/- 40 mL, 124 +/- 21 mL, respectively) were not statistically different from each other. There were no significant differences in the TEG values [reaction time (R), coagulation time (K), angle (alpha), and maximum amplitude (mA)] among the four groups at anytime nor was there any difference between the baseline, PARR, and 24-h TEG values within any group.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical TrialCombination of intramuscular Ketorolac and low dose epidural morphine for the relief of post-caesarean pain.
Epidural morphine produces profound analgesia but also causes many adverse effects in a dose-dependent manner. This double-blind, randomized, prospective study evaluated the analgesic efficacy and safety of low dose (2 mg) epidural morphine in combination with 30 mg intramuscular (IM) Ketorolac, a non-steroidal anti-inflammatory drug with potent analgesic activity, in patients suffering pain after caesarean surgery. Ninety parturients who received epidural anaesthesia in the postoperative period were divided into 3 equal groups: group A received epidural morphine 2 mg plus IM placebo; group B received epidural morphine 2 mg plus IM Ketorolac 30 mg; and group C received epidural saline placebo plus IM Ketorolac 30 mg. ⋯ Results showed that group B had statistically significant superior pain relief to that of the other 2 groups. The incidence of adverse effects was similar between those of group A and B. We concluded that the addition of Ketorolac by IM administration enhanced the analgesic effect of low dose (2 mg) epidural morphine in the relief of post-caesarean pain without potentiating its adverse effects.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural infusions of bupivacaine and fentanyl do not improve rehabilitation following one-stage bilateral total knee arthroplasty.
Epidural analgesia with local anaesthetic minimizes the catabolic response to surgery. To determine whether this could enhance the rate of recovery following orthopaedic surgery, 51 patients undergoing bilateral one-stage total knee arthroplasty were allocated to receive infusions of either continuous epidural bupivacaine/fentanyl or continuous intravenous fentanyl to compare the efficacy of these modes of pain relief on postoperative clinical outcomes and rates of rehabilitation. ⋯ Postoperatively, pain relief (visual analogue scale), attainment of physical therapy goals and cardiopulmonary complications were measured daily for 7 days. Epidural analgesia with a combination of bupivacaine and fentanyl did not result in any measurable improvement in rehabilitation milestones or reduction in postoperative complications following bilateral total knee arthroplasty than with fentanyl infusions alone.
