Effect of timing of morphine administration during propofol - remifentanil anesthesia on the requirements of post-operative analgesia.
An important concern of intra-operative infusion of remifentanil is the possible development of acute opioid tolerance, which manifests as an increased postoperative analgesia requirement. We have examined the effect of the timing of intra operative morphine administration on the need for morphine consumption for pain control during the first 24 hours after operation. ⋯ Early intra-operative administration of morphine compared to that of morphine in the end of surgery did not affect postoperative morphine consumption and pain scores during the first 24 hours after surgery for open nephrolithotomy. Newer pharmacologic interventions for prevention of acute tolerance of opioids seems rational (Clinical trial registration No. ACTRN: 12609000570280).

The analgesic effect of ultrasound-guided transverse abdominis plane block after laparoscopic totally extraperitoneal hernia repair.
The ultrasound-guided transverse abdominis plane block (TAPB) reduces postoperative pain after laparoscopic abdominal surgery. But, its effect post laparoscopic totally extraperitoneal hernia repair (TEP) is not clear. In this study, we evaluated the analgesic effect of ultrasound-guided TAPB in TEP. ⋯ The ultrasound-guided TAPB in patients that had undergone TEP reduced postoperative pain scores and the fentanyl requirement in the recovery room. Also, pain scores on coughing were reduced until postoperative 8 hours.

Minimum current requirement for confirming the localization of an epiradicular catheter placement.
Based on the necessity to confirm the epiradicular catheter misplacement, epiradicular threshold current for the confirmation of catheter tip localization is required. ⋯ We conclude that, threshold current for motor response seems to be lower for epiradicular compared with epidural placement, although we were not able to directly investigate the epidural threshold current. The threshold current of epiradicular space overlap that in the epidural space.

Cesarean section in spinal anesthesia on a patient with mesencephalic tumor and ventriculoperitoneal drainage -A case report-.
A seventeen-year-old pregnant woman with a mesencephalic tumor and ventriculoperitoneal (VP) drainage was admitted to the hospital at full term pregnancy to give birth. Elective cesarean section was performed because of her prime disease (mesencephalic tumor), breech position of the baby, gestational diabetes and expected weight of the baby of more than 4 kg. The operation was performed under spinal anesthesia. ⋯ The patient was hemodynamically stabile during the anesthesia and the procedure was uneventful. The woman developed no neurologic symptoms, and a healthy female child was born. This is the first case of a pregnant woman with a cerebral tumor and VP drainage on whom a successful delivery was performed with C-section under spinal anesthesia.

The effect of ketamine on the separation anxiety and emergence agitation in children undergoing brief ophthalmic surgery under desflurane general anesthesia.
Emergence agitation (EA) frequently occurs after desflurane anesthesia in children. Ketamine, because of its sedative and analgesic properties, might be useful for the management of separation anxiety and EA. We investigated the preventive effect of ketamine on separation anxiety and EA after desflurane anesthesia in children for brief ophthalmic surgery. ⋯ In children undergoing brief ophthalmic surgery with desflurane anesthesia, ketamine 1.0 mg/kg administered before entering the operating room reduced separation anxiety, postoperative pain, and incidence of EA without delay in recovery.
