Intraoperative and Postoperative Administration of Dexmedetomidine Reduces Anesthetic and Postoperative Analgesic Requirements in Patients Undergoing Cervical Spine Surgeries.
Early recovery from anesthesia and avoidance of analgesics with respiratory depressant properties are vital for maintenance of extubated airway in cervical spine surgeries. The current study investigated the role of dexmedetomidine as an anesthetic sparing agent and as a sole postoperative analgesic in these cases. ⋯ Dexmedetomidine lowered the anesthetic requirement with clinically permissible hemodynamic variations without undue prolongation of recovery time. Postoperative dexmedetomidine infusion provided effective analgesia without excessive sedation in patients undergoing cervical spine surgeries.

Observational StudyEvaluation of the Effect of Aneurysmal Clipping on Electrocardiography and Echocardiographic Changes in Patients With Subarachnoid Hemorrhage: A Prospective Observational Study.
Electrocardiographic (ECG) and echocardiographic changes that are subsequent to aneurysmal subarachnoid hemorrhage (a-SAH) are commonly observed with a prevalence varying from 27% to 100% and 13% to 18%, respectively. There are sparse data in the literature about the pattern of ECG and echocardiographic changes in patients with SAH after clipping of the aneurysm. Hence, we observed the effect of aneurysmal clipping on ECG and echocardiographic changes during the first week after surgery, and the impact of these changes on outcome at the end of 1 year. ⋯ The ECG changes, such as QTc prolongation, bradycardia, conduction abnormality, and echocardiographic changes, recover on postoperative day-1, in most of the cases after clipping. Patients with combined ECG and echocardiographic changes tend to have poor neurological outcome at the end of 1 year.

Laryngeal Mask Ventilation During Lumbar Spine Neurosurgery in Knee-Chest Position is Feasible.
This study describes our experience with laryngeal mask (LM) inserted after anesthetic induction in patients already in knee-chest position for lumbar neurosurgery. ⋯ LM airway management during lumbar neurosurgery in knee-chest position is feasible for selected patients when the anesthetist is experienced.

Review Meta AnalysisEffects of Acupuncture in Anesthesia for Craniotomy: A Meta-Analysis.
Acupuncture treatment has been used in China for >2500 years, and at present it is used worldwide as a form of analgesia in patients with acute and chronic pain. Furthermore, acupuncture is regularly used not only as a single anesthetic technique but also as a supplement or in addition to general anesthesia (GA). ⋯ The analysis suggests that the complementary use of acupuncture for craniotomy has additional analgesic effects, reduces the needed amount of volatile anesthetic, reduces the onset of postoperative nausea and vomiting, and might have protective effects on brain tissue. Our findings may stimulate future randomized controlled trials to provide definitive recommendations.
