To evaluate the efficacy, hemodynamic changes, and patient comfort during awake fiberoptic intubation done under combined regional blocks. ⋯ A properly performed technique of awake fiberoptic intubation done under combined regional nerve blocks provides good intubating conditions, patient comfort and safety and results in minimal hemodynamic changes.

Spinal anesthesia for cesarean section is not a 100% successful technique. At times, despite straightforward insertion and drug administration, intrathecal anesthesia for cesarean section fails to obtain any sensory or motor block. Very few studies and literature are available regarding repeat administration of spinal anesthesia and its drug dosage, especially after first spinal failure in cesarean section lower segment cesarean section (LSCS) due to fear of the excessive spread of drug. The aim of our study is to compare the outcome between two different doses of 0.5% hyperbaric bupivacaine repeated intrathecally after failed spinal. ⋯ Spinal anesthesia can be safely repeated in the cesarean section with 10 mg of 0.5% hyperbaric bupivacaine provided after first spinal anesthesia, the level of sensory block is below L4 and motor power in Bromage scale is 0.

Endotracheal tube (ETT) has been associated with various pharyngolaryngeal morbidities (PLMs) following general anesthesia (GA). Laryngeal mask airway (LMA), currently the most commonly used supraglottic airway device, has several advantageous over the ETT but has been associated with varying results of PLM. The aim of our study was to compare the PLM between them and to know whether LMA is a better alternative. ⋯ ETT was associated with an increased incidence of voice problems and sore throat whereas LMA had an increased incidence of dysphagia and odynophagia. Use of LMA changes the pharyngolaryngeal profile to a more acceptable one.

Difficult airway is one of the most challenging situations invariably encountered in modern anesthesia practice and requires a high level of skill. This case report highlights the use of video laryngoscopy as an assist device for lateral position intubation in a patient with a large lumbar mass who was unable to lie supine. This case emphasis the significance of careful approach to planning and preparation in the management of airway in such a case.

Intrathecal morphine provides effective postoperative analgesia, but their use is associated with numerous side effects, including pruritus, nausea, vomiting, urinary retention, and respiratory depression. Pruritus is the most common side effect with a reported incidence of 58-85%. ⋯ Nalbuphine and ondansetron were found to be more effective than placebo for prevention of intrathecal morphine-induced pruritus in women undergoing cesarean delivery and nalbuphine is preferred than ondansetron because it is not excreted in the breast milk.
