Randomized Controlled Trial Comparative Study Clinical TrialBilateral interpleural versus lumbar epidural bupivacaine-morphine analgesia for upper abdominal surgery.
This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. ⋯ There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

Randomized Controlled Trial Clinical TrialEffect of controlled hyperventilation on the pressor response to laryngoscopy and tracheal intubation.
Pressor response to laryngoscopy and tracheal intubation includes rises in blood pressure and heart rate. This response may be harmful in the presence of cerebral or myocardial diseases. Although different preventive measures have been developed the choice of the agent or method has not been defined clearly. ⋯ The pressor responses to laryngoscopy and tracheal intubation in hypocapnic and normocapnic groups were comparable. Moderate degrees of controlled hyperventilation caused relatively more fluctuation in blood pressure during induction of anesthesia. It can be concluded that controlled hyperventilation has no beneficial effect upon the pressor response to laryngoscopy and tracheal intubation.

Randomized Controlled Trial Clinical TrialHypobaric bupivacaine spinal anesthesia for cystoscopic intervention: the impact of adding fentanyl.
Addition of fentanyl to hyperbaric bupivacaine spinal anesthesia prolonged the duration of sensory block. This study seeks to test the hypothesis that adding fentanyl to small dose hypobaric spinal anesthesia will improve intraoperative patients and surgeon satisfaction without delay in recovery. ⋯ Spinal anesthesia with small dose (5 mg) hypobaric (0.1%) bupivacaine mixed with fentanyl (20 micrograms) produced adequate anesthesia for short cystoscopic procedures with minimal side effects and without delay in ambulation.

Randomized Controlled Trial Clinical TrialEvaluation of i.v. verapamil effects on cardiovascular responses in normotensive patients during laryngoscopy.
Laryngoscopy and intubation are known to increase systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR). In this study, we demonstrated that the injection of intravenous verapamil (0.1 mg/kg) prior to laryngoscopy can blunt the cardiovascular responses to laryngoscopy and intubation and result in stable hemodynamic profile in normotensive patients.

Kinking of an epidural catheter with resultant failure to inject drug is a complication of lumbar epidural analgesia. Here, we report a case of kinking of epidural catheter 1 cm proximal to its tip after 20 days of insertion. It was inserted to a female for pain relief, suffering from carcinoma of the cervix.
