Adjuvant drugs for peripheral nerve blocks are a promising solution to acute postoperative pain and the transition to chronic pain treatment. Peripheral nerve blocks (PNB) are used in the brachial plexus, lumbar plexus, femoral nerve, sciatic nerve, and many other anatomic locations for site-specific pain relief. However, the duration of action of a PNB is limited without an adjuvant drug. ⋯ The effects of the adjuvants on neurotoxicity must be further evaluated with further studies to delineate the safety in their use in PNB. Further research needs to be done. However, the use of adjuvants in PNB can be a way to help control postoperative pain.

Spinal anesthesia is the method of choice for the cesarean section. Hypotension is a common complication of this method. ⋯ Cesarean sections under spinal anesthesia in the lateral position than in the sitting position lead to a more rapid sensory and motor block, reduced ephedrine consumption, and enhanced satisfaction of women.

Gastric ultrasound is an emerging tool for preoperative evaluation of gastric content and volume. ⋯ Despite the differences in CSA between obese and normal-weight participants in both positions (obese > normal-weight), both groups showed a low predicted gastric residual volume < 1.5 mL/kg and were at low risk for aspiration, provided that fasting was initiated at least 8 hours before elective surgery.

Aspiration is one of the important complications of general anesthesia, although infrequent as well as accompanying high morbidity and mortality. The volume of gastric content is considered as a risk factor in this regard. Therefore, it is normally mostly recommend to consider proper fasting time before induction of general anesthesia. ⋯ In the current study in which ultrasonographic indexes, including GAG and CSA, were assessed as a suboptimal gastric emptying test method, it was found that metoclopramide could accelerate gastric emptying compared to placebo in patients with incomplete fasting before induction of general anesthesia.

The volume of pediatric Procedural Sedation and Analgesia (PSA) outside the operating room has been increasing. This high clinical demand leads non-anesthesiologists, especially pediatric intensivists, pediatricians, and emergency physicians, to take a role in performing procedural sedation. Our department has established the PSA service by pediatric intensivists since 2015. ⋯ Our data suggest that children who undergo procedural sedation outside the operating room conducted by pediatric intensivists are safe and effectively treated. Receiving more than three sedative medications is the independent risk factor associated with serious adverse events.
