Comparing the posture and comfort of anaesthesiologists during laryngoscopy and tracheal intubation in the head-elevated laryngoscopy position in supine position and with a 25° backup: A randomised clinical crossover trial.

Background And Aims: The head-elevated laryngoscopy position (HELP) and a 25° backup have been proposed to enhance glottic visualisation, yet concerns about ergonomic discomfort hinder their widespread adoption. This study compares the comfort and posture adopted by anaesthesiologists while performing laryngoscopy and tracheal intubation with patients in HELP while in a supine position or with 25° backup.

Methods: The study included 48 patients aged 18-60 years with normal airways and 12 experienced anaesthesiologists.

Additional muscle fibers of brachioradialis with anomalous high origin and entrapment of radial nerve in an osseomuscular canal.

Normally, brachioradialis originates from the upper part of the lateral supracondylar ridge of the humerus. Variations in its origin are very rare. We observed the presence of an additional set of fleshy muscle fibers in the lateral part of the anterior compartment of the arm in addition to the other normal muscles.

Persistent sacrococcygeus ventralis muscle in an adult human pelvic wall: a variation for surgeons to note.

Occurrence of abnormal muscles in the pelvic wall is very rare. During a routine dissection of the pelvic wall, an abnormal muscle referred to as sacrococcygeus ventralis was noted in a 65-year-old South Indian cadaver. The fleshy fibers of the muscle were arising from the lateral part of the ventral surface of the sacrum at the level of S3 segment.
