Anesthesia, essays and researches

Conscious sedation is the key for successful AFOI. This trial was conducted to compare the effectiveness of dexmedetomidine and low dose of ketamine against propofol and low dose ketamine. ⋯ The concomitant administration of low dose of ketamine with dexmedetomidine had better intubation time and sedation scores with higher patient satisfaction scores than the combination of propofol and low dose of ketamine.

Clonidine, an alpha2 agonist, when added to local anesthetics in different regional and neuraxial blocks reduces the onset time, improves the efficacy, and increases the duration of postoperative analgesia. ⋯ The inclusion of 100 μg of clonidine with bupivacaine in ultrasound-guided supraclavicular brachial plexus blocks prolongs both sensory and motor blockade. It also provides significant postoperative analgesia and mild sedation which is beneficial in the immediate stressful postoperative period.

Axillary brachial plexus block (ABPB) is safest among other methods of brachial plexus block because of its ease and reliability. The two approaches of ultrasonography-guided ABPB are perivascular (PV) and perineural (PN). ⋯ Ultrasound-guided PV axillary plexus block is better than PN axillary plexus block with respect to performance time and number of needle passes; but onset time was shorter in PN block, with precaution eliminating the risk of complications.

General anesthesia is preferred for clavicular surgeries. With the advent of ultrasound-guided technology, interscalene brachial plexus block with superficial cervical nerve block has become a new option for providing intraoperative anesthesia and postoperative analgesia for surgeries of the clavicle. ⋯ Ultrasound-guided interscalene brachial plexus block combined with superficial cervical nerve block is a safe and effective mode of anesthesia in comparison to general anesthesia for clavicle surgeries.

Evaluation of Ultrasound-Guided Erector Spinae Plane Block and Oblique Subcostal Transversus Abdominis Plane Block in Laparoscopic Cholecystectomy: Randomized, Controlled, Prospective Study.
Oblique subcostal transversus abdominis plane block (OSTAP) is a recently described regional anesthetic technique used in upper abdominal surgeries such as laparoscopic cholecystectomy (LC). Erector spinae plane block (ESPB) has also been reported for postoperative analgesia in LC. ⋯ Bilateral ultrasound-guided ESPB and OSTAP performed at the end of LC lead to akin analgesia requirement and improve the quality of multimodal analgesia.
