Clinical Trial Controlled Clinical Trial[Interscalenic block and surgery of the shoulder. A prospective study of a continuous series of 167 patients].
To determine the relationship between minimal stimulating current and success rate of interscalene brachial plexus block (IBPB), to assess the quality of anaesthesia and postoperative analgesia, and to evaluate the benefits and drawbacks of this technique in shoulder surgery. ⋯ The correlation between minimal stimulating current and success rate has clearly shown the benefit of the nerve stimulation. IBPB, which provides a successful and efficient anaesthesia with minimal risk and satisfactory postoperative analgesia, has become the standard technique for shoulder surgery.

Comparative Study Clinical Trial
Interscalene anesthesia for shoulder arthroscopy in a community-sized military hospital.
The first 100 consecutive shoulder arthroscopic procedures performed under interscalene anesthesia at a small community-sized military hospital are the basis of this report. This method of anesthesia was compared with 100 shoulder arthroscopies performed in a previous 2-year time period under general anesthesia. A variety of arthroscopic and subsequent open reconstructive procedures about the shoulder were performed using both techniques. ⋯ Ten patients who had previous shoulder surgery under general anesthesia preferred the interscalene method. In summary, interscalene anesthesia proved to be an excellent method of anesthesia for shoulder arthroscopy. The technique is reproducible within the resources available in most community-level hospitals.

Randomized Controlled Trial Clinical TrialThe effect of bupivacaine skull block on the hemodynamic response to craniotomy.
The placement of pointed cranial pins into the periosteum is a recognized acute noxious stimulation during intracranial surgery which can result in sudden increases in blood pressure and heart rate, causing increases in intracranial pressure. A skull block (blockade of the nerves that innervate the scalp, including the greater and lesser occipital nerves, the supraorbital and supratrochlear nerves, the auriculotemporal nerves, and the greater auricular nerves) may be effective in reducing hypertension and tachycardia. Twenty-one patients were allocated in a prospective, double-blind fashion to a control group or a bupivacaine group. ⋯ Systolic (SAP), diastolic (DAP), mean arterial pressure (MAP), heart rate (HR), and end-tidal isoflurane were recorded at the following times: 5 min after the induction of anesthesia, during performance of the skull block, during head pinning, and 5 min after head pinning. Significant increases in SAP of 40 +/- 6 mm Hg, DAP of 30 +/- 5 mm Hg, MAP of 32 +/- 6 mm Hg, and HR of 22 +/- 5 bpm occurred during head pinning in the control group, while remaining unchanged in the bupivacaine group. These results demonstrate that a skull block using 0.5% bupivacaine successfully blunts the hemodynamic response to head pinning.

Randomized Controlled Trial Clinical Trial
Prospective randomized study of a new method of providing postoperative pain relief following femoropopliteal bypass.
The extensive incision required for femoropopliteal bypass using saphenous vein causes significant postoperative pain, principally within the distribution of the cutaneous branches of the femoral nerve. This prospective randomized study investigated the efficacy of continuous postoperative femoral nerve block in reducing both pain (visual analogue pain score) and the requirement for opiate analgesia. ⋯ Postoperative pain was effectively abolished in the former group. The addition of a nerve block to PCA provides superior pain control after femoropopliteal bypass.
