Adductor canal block is a regional anesthetic block procedure commonly employed for knee surgeries. This study aims at locating the adductor canal precisely which will be of great use for the surgeons operating on knee. ⋯ This study suggests that a point more than 3 cm below the midpoint of thigh will be the ideal location for the approach of adductor canal block.

Erector spinae plane (ESP) block is a promising technique in the field of pediatric postoperative analgesia considering its safety and simplicity. ⋯ The findings suggest that US guided ESP block resulted in a more effective and longer duration of postoperative analgesia following a pediatric unilateral inguinal hernia repair compared to IIN block.

Perineural dexamethasone has been shown to improve analgesia in single injection supraclavicular block. Systemic mechanism of action of dexamethasone along with safety concerns of perineural route of administration has prompted the investigation of intravenous route as an alternative. ⋯ It is concluded from this study that intravenous and perineural dexamethasone equally prolongs the duration of analgesia in supraclavicular block. However, perineural dexamethasone resulted in a faster onset of motor and sensory blockade.

Laparoscopic hysterectomy operations especially for obese patients necessitate Trendelenburg position and pneumoperitoneum with carbon dioxide, which could affect cardiac and pulmonary functions. The present study aimed to compare the impact of pressure-controlled ventilation with volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV) with equal ratio ventilation (ERV), i.e., I: E ratio of 1:1 on hemodynamics, respiratory mechanics, and oxygenation. ⋯ In obese females undergoing laparoscopic hysterectomy surgeries, PCV-VG was superior to VCV with ERV as it provided higher dynamic compliance and lower peak inspiratory pressure that could be preferable, especially in those patients in whom cardiopulmonary function could be more susceptible to impairment.

Postspinal hypotension remains a frequent complication of subarachnoid block during cesarean section causing further maternal and fetal adverse effects. ⋯ NASG proved to be a more effective device for prevention of postspinal hypotension when compared with application of SCD or no device.
