Randomized Controlled Trial Comparative Study Clinical TrialIs intercostal block for pain management in thoracic surgery more successful than epidural anaesthesia?
Currently epidural anesthesia is the gold standard for postoperative pain management in thoracic surgery. In a prospective randomised study, the effect of an intercostal nerve block applied at the end of the operation was compared to that of epidural anesthesia. ⋯ Pain management by intercostal block was superior during the first 24h after surgery whereas on the second day after surgery pain control was significantly better achieved by the epidural catheter in relaxed position. A combination of both forms of anaesthesia seems to be an ideal pain management in patients undergoing thoracic surgery.

Epidural bolus injection with alkalinized lidocaine improves blockade of the first sacral segment--a brief report.
It has been reported that the addition of epinephrine and/or bicarbonate to local anesthetic enhances the depth of epidural blockade and that initial partial bolus injection results in greater caudal spread. We evaluated the anesthetic effects of lidocaine with epinephrine and/or bicarbonate injected into the epidural space by bolus or catheter injection. ⋯ Epidural bolus injection of lidocaine-bicarbonate with epinephrine improves the pain threshold and speeds the onset of the blockade of the first sacral region.

The epidural and subarachnoid spaces should be identified at the first attempt, since multiple punctures increase the risk of postdural puncture headache, epidural haematoma and neural trauma. The study aimed to describe the predictors of successful neuraxial blocks at the first attempt. ⋯ The successful location of the subarachnoid or the epidural space at the first attempt is influenced by the quality of patients' anatomical landmarks, the adequacy of patient positioning and the provider's level of experience.

Central neuraxial blockade promotes external cephalic version success after a failed attempt.
External cephalic version (ECV) has been successfully used to decrease the fetal and maternal morbidity and costs of cesarean delivery. As there are limited data regarding the use of central neuraxial blockade in the setting of previously failed ECV attempts, we sought to evaluate the efficacy and safety of spinal and epidural anesthesia in this setting. A retrospective review of all ECV attempts performed by a single experienced obstetrician between 1995 and 1999 was conducted. Standardized tocolytic and anesthetic regimens were used. A total of 77 patients underwent ECV attempts; of these, 37 (48%) were unsuccessful, 15 of which consented to further attempts with anesthesia. Neuraxial anesthesia was associated with frequent ECV success in both multiparous 4/4 (100%) and nulliparous 9/11 (82%) parturients. Overall 5/6 (83%) and 8/9 (89%) (P = NS) ECV attempts were successful with spinal and epidural anesthesia, respectively, with 2/5 (40%) and 6/8 (75%) (P = NS) resulting in vaginal deliveries. One successful ECV in the epidural group had an urgent cesarean delivery for persistent fetal bradycardia with good neonatal and maternal outcomes. We conclude central neuraxial anesthesia promotes successful ECV after previously failed ECV attempts. ⋯ Our retrospective analysis of central neuraxial techniques, both epidural and spinal anesthesia, noted a significant success rate in the setting of previously failed external cephalic version attempts.

Clinical TrialBlockade of branches of the ophthalmic nerve in the management of acute attack of migraine.
The aim of this study was the evaluation of the blockade of branches of ophthalmic nerve in the management of the acute attack of migraine headache localized to the ocular region. The study included 70 female patients 23-60 years old who presented to the pain clinic at our hospital with an acute attack of migraine headache localized to the ocular and retro-ocular region. A targeted history and a neurologic examination were performed in all patients to confirm the diagnosis and at the same time to rule out life-threatening neurological dysfunction. ⋯ The migraine acute attack was relieved in 58/70 patients (82%), while in 12/70 patients (18%) the results were poor. The pain relief started 3-4 min after the injection and was completed in 10-15 min. Our results support that the blockade of the branches of the ophthalmic nerve seems to be a safe and effective technique in the management of the acute attack of migraine localized to the ocular and retro-ocular region.
