RESUMO
The breakage of an epidural catheter, which is usually not noticed, is a rare but important complication encountered while inserting or removing the catheter during epidural blockade. While the epidural catheter was being inserted for labor analgesia, despite no problem being encountered in advancing the catheter, it was drawn back to verify the location; it was observed that 2 cm of the distal end of the catheter was missing. A neurosurgical consultation was requested; it was reported that the broken piece would not create any problems and reintervention could be performed for labor analgesia. An epidural catheter was reinserted and was used for analgesia without any problem until delivery. Although nine months have passed, no problem was defined by the patient. If epidural catheter has to be removed while the Tuohy needle is still in place, we recommend that they should be removed together to minimize the risk of a possible breakage. We think that the decision for surgery and imaging can be performed based on the individual patient's clinical picture.
RESUMO
UNLABELLED: We investigated, in a randomized, placebo-controlled, double-blind study, the efficacy and safety of gabapentin on pain after abdominal hysterectomy and on tramadol consumption in patients. The 50 patients were randomized to receive either oral placebo or gabapentin 1200 mg 1 h before surgery. Anesthesia was induced with propofol and maintained with sevoflurane in 50% N(2)O/O(2) with a fresh gas flow of 2 L/min (50% N(2)O in O(2)) and fentanyl (2 microg/kg). All patients received patient-controlled analgesia with tramadol with a 50 mg initial loading dose, 20 mg incremental dose, 10-min lockout interval, and 4-h limit of 300 mg. The incremental dose was increased to 30 mg if analgesia was inadequate after 1 h. Patients were studied at 4, 8, 12, 16, 20, and 24 h for visual analog (VAS) pain scores, heart rate, peripheral oxygen saturation, mean arterial blood pressure, respiratory rate, sedation, and tramadol consumption. The VAS scores in the sitting and supine position at 1, 4, 8, 12, 16, and 20 h were significantly lower in the gabapentin group when compared with the placebo group up to 20 h after surgery. The tramadol consumption at 12, 16, 20, and 24 h and total tramadol consumption were significantly less in the gabapentin group when compared with placebo group. Sedation scores were similar at all the measured times. There were no differences between groups in adverse effects. Preoperative oral gabapentin decreased pain scores and postoperative tramadol consumption in patients after abdominal hysterectomy. IMPLICATIONS: This randomized, controlled trial examined the effects of preoperative oral gabapentin 1200 mg on postoperative pain and tramadol consumptions. We conclude that preoperative oral gabapentin is effective in reducing postoperative pain scores and tramadol consumption in patients after abdominal hysterectomy.
