Complications and unexpected events related to prone positioning or inhaled sedation

Patient number	Type of complication	Reason	Management	Result
063	Pharyngeal dislocation of endotracheal tube	Unclear whether the patient extubated herself with her tongue or fixation of the tube unsticked because of salivation	Already spontaneous breathing → Noninvasive Ventilation, turned back, re-intubation	No hypoxia, turned back in PP after re-intubation
019	Insufficient sedation	Technical defect of Anaconda	Dexmedetomidine infusion	PP continued
094	Insufficient sedation	Low tidal volume	Sufentanil infusion	PP continued
095	Insufficient sedation	Low tidal volume	Sufentanil infusion	PP continued
056	Respiratory acidosis	Unclear	Controlled ventilation → still acidodic → turned back to supine position, Anaconda removed	Still acidotic in supine position
072	Respiratory acidosis	Retrospectively: kinked tube	Turned back, refixation of tube	PP continued

PP Prone positioning
