[Effect of continuous interscalene block with ropivacaine at a low concentration on postoperative pain relief after arthroscopic rotator cuff reconstruction].

Background: The analgesic effect of continuous interscalene block with ropivacaine at a low concentration was compared with that of single-shot interscalene block after arthroscopic rotator cuff reconstruction (ARCR).

Methods: Eighty patients scheduled to undergo ARCR from January 2010 to March 2012 were assigned to a group receiving postoperative continuous interscalene block (continuous group, n=46) and a group receiving single-shot interscalne block (single group, n=34). In both groups, ultrasound-guided interscalene block was performed before induction of general anesthesia.

[Effect of single-shot interscalene block with less than 10 ml of local anesthetics on postoperative pain relief after arthroscopic rotator cuff reconstruction].

Background: The effect of interscalene block on postoperative pain after arthroscopic rotator cuff reconstruction (ARCR) was evaluated.

Methods: Eighty-four patients scheduled to undergo ARCR from April 2008 to March 2010 were assigned to a group receiving interscalene block with general anesthesia (Block group, n = 49) and a group receiving general anesthesia solely (General group, n = 35). In the Block group, ultrasound-guided single-shot interscalene block was performed before induction of general anesthesia with 0.

[Postoperative pancreatitis after total hip replacement under general anesthesia].

A 61 year old male patient developed postoperative pancreatitis after total hip replacement under general anesthesia with sevoflurane. The patient had chronic renal failure and was receiving hemodialysis. The estimated intraoperative blood loss was 1500 ml, and 1200 ml of blood was administered.

[Sudden cardiac arrest after induction of general anesthesia: a case report].

We experienced sudden cardiac arrest after induction of general anesthesia using isoflurane. The patient had had paroxysmal atrial fibrillation for one year and had been treated with digoxin and cibenzoline succinate. Sinus rhythm appeared soon after the start of closed chest compression.
