Clinical screening tests were included to define a difficult laryngoscopy such as history of difficult or impossible intubation, NC, MMS, retrognathia, protrusion of the upper incisors, TMD, mouth opening, dentition, macroglossia, presence of a beard, UBLT, spine mobility and palm print test for diabetes.
Ultrasound airway assessment was performed: Clinical screening tests were included to define a difficult laryngoscopy such as history of difficult or impossible intubation, NC, MMS, retrognathia, protrusion of the upper incisors, TMD, mouth opening, dentition, macroglossia, presence of a beard, UBLT, spine mobility and palm print test for diabetes.
Ultrasound airway assessment was performed Three parameters were measured to calculate the scores: Tongue thickness (TT) in coronal plane, Distance from the skin to hyoid bone (SHB), Distance from the skin to the thyrohyoid membrane (STM). Two scores were developed from a study conducted in 2019. The first score, to predict a difficult laryngoscopy, uses two parameters: the modified MALLAMPATI class (MMS) and the STM. A score strictly greater than 2 is predictive of a difficult laryngoscopy. The second score, to predict difficult ventilation, uses four parameters: BMI, NC, TT in coronal plane, and SHB. A score strictly greater than 20 is predictive of difficult ventilation. A well-experienced anesthesiologist performed a direct laryngoscopy and graded it as Cormack-Lehane's grading.
Difficulty in intubation and/or mask ventilation was managed according to the 2017 SFAR guidelines.

A prospective, bicentric, randomized, double-blind controlled study including parturients scheduled for elective caesarean delivery under spinal anaesthesia and randomized and assigned to one of the two groups:
Group O ondansetron : receiving Intravenous (IV) ondansetron 0.10 mg/ kg diluted in 5 ml normal saline, 5 min before spinal anesthesia Group C control : receiving IV normal saline 5 ml (control group) 5 min before spinal anesthesia
OBJECTIVE :
To evaluate the efficacy of ondansetron in preventing post-dural puncture headache after spinal anaesthesia for caesarean section.

Prospective observationnal study, including ICU adult patients with invasive mechanical ventilation for at least 48 hours. Patients are included when performing weaning from mechanical ventilation with pressure support (lowest level of pressure support).
Before separating the patient from the ventilator and performing a T tube spontaneous breathing test, diaphragm ultrasound is performed bilaterally : diaphragm excursion, diaphragm thickening fraction and maximal contraction and relaxation velocities with tissue doppler imaging.
