Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of bupivacaine plus buprenorphine with bupivacaine alone by caudal blockade for post-operative pain relief after hip and knee arthroplasty.
In a double-blind, parallel group trial, 15 patients who were given a caudal injection of 1.8 mg kg-1 of bupivacaine after induction of anaesthesia, were compared with 15 patients in whom 7.2 mg kg-1 of buprenorphine was added to the same dose of bupivacaine, prior to knee or hip replacement surgery. The duration of analgesia was much longer (mean 606 min vs. 126 min P < 0.001) in those receiving added buprenorphine; mean morphine consumption in the first 24 h was halved (14 mg vs. 28 mg) and patient satisfaction greatly increased. There were no significant differences in the incidence of complications although the group which had added buprenorphine had a lower incidence of vomiting.

Randomized Controlled Trial Comparative Study Clinical Trial
Doxacurium block is not influenced by age.
To determine the influence of aging on the efficacy and safety of doxacurium. ⋯ The use of doxacurium in elderly patients is possible with no need for dose adjustment. Doxacurium might be a good choice for patients with cardiac disease who are scheduled for long surgical procedures.

Randomized Controlled Trial Clinical TrialDouble-blind randomized evaluation of intercostal nerve blocks as an adjuvant to subarachnoid administered morphine for post-thoracotomy analgesia.
Thoracotomy is associated with pain and compromised pulmonary function. Intercostal nerve blocks (INB) and subarachnoid morphine (SM) act on different portions of the pain pathway. Each is effective for post-thoracotomy pain relief. The combination of these two modalities in relieving post-thoracotomy pain and improving postoperative pulmonary function has not been investigated. ⋯ Although postoperative INB provided modest improvements in pain and pulmonary function when used as an adjuvant to 0.5 mg SM for post-thoracotomy analgesia, the benefits were transient. The authors do not recommend adding INB for patients undergoing lateral thoracotomy who receive 0.5 mg SM.

During general anesthesia, different modes of nerve stimulation are used for estimation of the degree of neuromuscular blockade. When switching between the different modes, it is important to know whether the preceding mode influences the responses to the succeeding mode, and if so, for how long. The object of our study was to determine the number of stimulations required for stabilization of the muscular response when switching between double-burst stimulation (DBS) applied every 20 sec, train-of-four (TOF) applied every 12 sec, and posttetanic count (PTC) at surgical degrees of neuromuscular blockade. ⋯ When switching from DBS to TOF, 4 to 7 stimulations (56 to 92 sec) were required for stabilization of the T1 response. When switching from TOF to DBS, 3 stimulations (36 to 52 sec) were required for stabilization of the D1 response, and, finally, when switching from PTC to DBS, 5 to 11 stimulations (81 to 201 sec) were required for stabilization of the D1 response. Stabilization of D1 was faster following TOF than following PTC (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

A local anaesthetic block of branches of the greater auricular and auriculotemporal nerves was used to facilitate the extraction of retained butterfly backs and ear-ring studs. A total of 28 ear blocks were performed on 26 patients. ⋯ Assessment of analgesia was not possible in one 5-year-old child. We recommend this quick and simple technique for removal of retained ear-rings, particularly when there is associated soft tissue infection, in which case infiltration of local anaesthetic into the earlobe is contraindicated.
