The pattern of clinical findings and electrocardiography (ECG) changes known as Wellens' syndrome is associated with significant stenosis of the proximal left anterior descending coronary artery. Cases can be classified according to the ECG pattern into type 1 (biphasic T waves) or type 2 (deeply inverted T waves, especially in leads V2 and V3). We present here an unusual case of Wellens' syndrome in which the ECG pattern changed from type 2 to type 1 during observation, and in which the coronary lesion was in the middle rather than the proximal part of the left anterior descending artery.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of prophylactic anti-emetic effects of ondansetron and dexamethasone in women undergoing day-case gynaecological laparoscopic surgery.
We aimed to determine the effect of ondansetron and dexamethasone on preventing post-operative nausea and vomiting (PONV). Sixty women undergoing laparoscopic gynaecological surgery were randomized to receive ondansetron 4 mg, dexamethasone 8 mg or saline. Drugs were administered 2 min before induction of anaesthesia, and anaesthesia and post-operative analgesic regimens were standardized. ⋯ In this period, ondansetron was significantly more effective than dexamethasone and saline, but no differences were seen between dexamethasone and saline. In all treatment groups, post-operative visual analogue scale scores, sedation scores and usage of analgesics were similar. In conclusion, ondansetron, but not dexamethasone, prevented PONV in the first 3 h after gynaecological laparoscopic surgery.

Randomized Controlled Trial Clinical Trial
The effect of caudal bupivacaine versus tramadol in post-operative analgesia for paediatric patients.
In this study 20 paediatric surgical patients were randomized to two groups after induction of general anaesthesia. Group 1 received 0.25% bupivacaine (2 mg/kg) and group 2 received 5% tramadol (2 mg/kg) both as a caudal block. Heart rate, mean arterial pressure, arterial oxygen saturation, respiratory rate and pain and sedation scores were recorded at 1, 2, 4, 6, 12 and 24 h post-operatively. ⋯ The pain and sedation scores in group 2 were significantly lower compared with group 1. There were no significant differences in heart rate, mean arterial pressure, arterial oxygen saturation and respiratory rate between the two groups. In conclusion, caudal tramadol was superior to bupivacaine in analgesic efficacy and in reducing the need for additional analgesia during the post-operative period in paediatric patients.
