Clinical Trial
Evaluation of the lateral modified approach for continuous interscalene block after shoulder surgery.
Continuous interscalene block is the technique of choice for postoperative pain relief treatment after shoulder surgery. The authors prospectively evaluated the modified lateral approach for the performance of the interscalene catheter block and monitored 700 patients for clinical efficacy and complications during the first 6 months after placement of the catheter. ⋯ The lateral modified approach provides good conditions for placement of the interscalene catheter. Anesthesia and analgesia performed through the catheter are efficient. The rates of infection and neurologic complications are low, and patient satisfaction is high.

Comparative Study Clinical Trial
Predicting recovery from deep neuromuscular block by rocuronium in the elderly.
To determine the influence of aging on the relationship between posttetanic count (PTC) and train-of-four (TOF) response during intense neuromuscular blockade caused by rocuronium. ⋯ Posttetanic twitch stimulation is a useful method of monitoring intense neuromuscular blockade caused by rocuronium in both age groups. The interval between the earliest appearance of a posttetanic response and the first response to TOF stimulation (T1) is greater in the elderly than in the young.

Case ReportsCardiac arrest after interscalene brachial plexus block with ropivacaine and lidocaine.
Serious adverse reactions to ropivacaine and lidocaine are rare. In this report, we describe a case of sudden cardiac arrest after an interscalene brachial plexus block with a mixture of 150 mg of ropivacaine and 360 mg of lidocaine in a previously healthy, 34-year-old, 97-kg man. ⋯ He eventually made a good recovery. We conclude that although ropivacaine and lidocaine are often considered relatively safe local anesthetics, serious cardiovascular complications can occur after the use of these drugs.

Comparative Study
Comparing the effects of femoral nerve block versus femoral and sciatic nerve block on pain and opiate consumption after total knee arthroplasty.
The goal of this study was to compare femoral and femoral plus sciatic nerve blocks in the postoperative pain management of patients undergoing total knee arthroplasty (TKA). A total of 97 patients participated in a convenience sample, comparative study. Patients who received femoral nerve block only (n = 30) reported statistically higher pain scores (P <.05) and showed 61% higher opiate consumption than those who received femoral and sciatic nerve blocks (n = 67) in the first 24 hours after surgery. The results suggest that the combined femoral and sciatic nerve block provides superior pain management in the early postoperative period after TKA.

[Maxillary nerve block for zygoma and orbital floor fractures reduction].
There are few reports of zygomatic orbital floor or zygomatic arch fractures reduction under regional anesthesia. This study aimed at evaluating extraoral maxillary nerve block for zygoma and orbital floor fractures reduction. ⋯ Zygomatic fractures reduction is feasible under maxillary nerve block when performed in pterygopalatine fossa inducing anesthesia in its two distal branches: zygomaticotemporal and zygomaticofacial nerves.
