Randomized Controlled Trial Comparative Study
Norepinephrine or phenylephrine for the prevention of post-spinal hypotension after caesarean section: A double-blinded, randomized, controlled study of fetal heart rate and fetal cardiac output.
Spinal anesthesia often causes hypotension, with consequent risk to the fetus. The use of vasopressor agents has been highly recommended for the prevention of spinal anesthesia-induced hypotension during caesarean delivery. Many studies have shown that norepinephrine can provide more stable maternal hemodynamics than phenylephrine. We therefore tested the hypothesis that norepinephrine preserves fetal circulation better than phenylephrine when used to treat maternal hypotension consequent to spinal anesthesia. ⋯ Prophylactic infusion of comparable doses of phenylephrine or norepinephrine has similar effects on fetal heart rate and cardiac output changes after spinal anesthesia. Neither phenylephrine nor norepinephrine has meaningful detrimental effects on fetal circulation or neonatal outcomes.

ReviewChronic consequences of accidental dural puncture and postdural puncture headache in obstetric anaesthesia - sieving through the evidence.
Accidental dural puncture (ADP) and postdural puncture headache (PDPH) are relatively common complications of neuraxial anaesthesia and analgesia in obstetrics. Both may result in acute and chronic morbidity. This review intends to discuss the chronic implications of ADP and PDPH and raise awareness of severe and potentially life-threatening conditions associated with them. ⋯ Many clinicians still believe that ADP and PDPH are benign and self-limiting conditions whereas there may be serious and devastating consequences of both. It is imperative that all women with ADP and PDPH are appropriately diagnosed and treated.

Randomized Controlled TrialEfficacy of Single-Bolus Administration of Remimazolam During Induction of Anesthesia in Patients Undergoing Cardiac Surgery: A Prospective, Single-Center, Randomized Controlled Study.
Remimazolam is a recently marketed ultrashort-acting benzodiazepine. This drug is considered safe and effective during general anesthesia; however, limited information is available about its effects on patients undergoing cardiac surgery. Therefore, the present study was conducted to evaluate the efficacy and hemodynamic stability of a bolus administration of remimazolam during anesthesia induction in patients undergoing cardiac surgery. ⋯ A single-bolus injection of remimazolam provided efficient anesthetic induction in patients undergoing cardiac surgery. A 0.2 mg/kg bolus injection of remimazolam resulted in the shortest time to loss of responsiveness among the 3 groups, without significantly altering the hemodynamic parameters. Therefore, this dosing can be considered a favorable anesthetic induction method for patients undergoing cardiac surgery.

ReviewCritical care innovations: navigating pain relief in intensive care: the role of regional anesthesia.
The purpose of this article is to provide an update of regional anesthesia and its applications in the critical care patient population. ⋯ Pain management in the ICU is an important and sometimes challenging aspect of patient care. Regional anesthetic techniques have more indications and are safe, versatile tools that should be incorporated into care of critically ill patients.

ReviewThe use of honey in the perioperative care of tonsillectomy patients-A narrative review.
Tonsillectomy is one of the most common surgical procedures in childhood. While generally safe, it often is associated with a difficult early recovery phase with poor oral intake, dehydration, difficult or painful swallowing, postoperative bleeding, infection and/or otalgia. Better pain management and the availability of more child friendly medications are within the top consumer priorities in perioperative medicine, highlighting the importance of alternative pain treatments. ⋯ Effect sizes ranged from small to huge across the studies. While the application of honey post-tonsillectomy may offer analgesic and healing benefits, it may also reduce postoperative bleeding. However, while there are potential benefits based on the chemical composition of honey, the current literature is of variable quality and there is need for high quality clinical trials.
