Diagnostic Accuracy of Ultrasound Measurements of Anterior Neck Soft Tissue in Determining a Difficult Airway.

Context: Airway management in the emergency department is challenging because conventional screening tools cannot be applied. Therefore, a rapid noninvasive means of identifying a difficult airway will be advantageous for emergency physicians.

Aims: The aim of this study is to examine the association between ultrasound measurements of anterior neck soft tissue and difficult airway as judged by the Cormack Lehane grading.

Comparision of efficacy of sufentanil and fentanyl with low-concentration bupivacaine for combined spinal epidural labour analgesia.

Objectives: The highly lipid-soluble opioids, sufentanil and fentanyl, are used in combination with low-concentration bupivacaine to provide combined spinal epidural (CSE) analgesia during labour. We designed a prospective, randomized, single-blind study to compare the efficacy of these two opioids with bupivacaine in terms of the quality of analgesia, side-effects and maternal and foetal outcome.

Methods: Sixty parturients requesting labour analgesia were divided into two groups randomly.
