Tongue symptoms, suspension force and duration during operative laryngoscopy

Medico-legal liability of injuries arising from laryngoscopy

OBJECTIVE

Dental and mucosal injuries from laryngoscopy in the peri-operative period are common medico-legal complaints. This study investigated lawsuits arising from laryngoscopy.

METHODS

Westlaw, a legal database containing trial records from across the USA, was retrospectively reviewed. Plaintiff and/or defendant characteristics, claimed injuries, legal outcomes and awards were extracted.

RESULTS

Of all laryngoscopy-related dental or mucosal injuries brought before a state or federal court, none (0 per cent) resulted in a defence verdict against the provider or monetary gain for the patient. Rulings in the patient's favour were observed only when laryngoscopy was found to be the proximate cause of multiple compounding complications that culminated in severe medical outcomes such as exsanguination, septic shock or cardiopulmonary arrest.

CONCLUSION

Proper laryngoscopy technique and a robust informed-consent process that accurately sets patients' expectations reduces litigation risk. Future litigation pursuits should consider the low likelihood of malpractice allegation success at trial.

A comparative evaluation of the sniffing, the simple head extension and the head hyperextension positions for laryngoscopic view and intubation difficulty in adults undergoing direct laryngoscopy

OBJECTIVE

This work aimed to compare between the laryngoscopy positions; sniffing, simple head extension and head hyperextension positions to assess whether the laryngeal view, intubation time and intubation difficulty could improve with one of these positions than the others.

DESIGN

Prospective randomized three arms clinical trial.

SETTING

Operation room, the phoniatrics unit [removed for blind peer review].

PARTICIPANTS

The study included 75 cases with 25 cases in each group. Group "A" with head in the sniffing position, Group "B" with the head in simple extension position, Group "C" with head in hyperextension position.

RESULTS

The three groups were compared regarding intubation time and laryngoscopic view time. Intubation time showed statistically significant difference between the three groups. Mean of sniffing group (No. = 25) was 13.19 s (± 3.35). Mean of simple extension group (No. = 25) was 11.29 s (± 3.14). Mean of Hyperextension group (No. = 25) was 14.39 s (± 4.14). Laryngoscopic view time showed statistically highly significant difference between the three groups. Mean of sniffing group (No. = 25) was 17.19 s (± 7.27). Mean of simple group (No. = 25) was 12.18 s (± 4.46). Mean of hyperextension group (No. = 25) was 17.08 s (± 6.51).

CONCLUSION

Comparing the sniffing, the simple extension and the hyperextension positions, the simple extension position showed the best time regarding intubation time and laryngoscopic view time.

Informed consent for suspension microlaryngoscopy: what should we tell the patient? A consensus statement of the European Laryngological Society

INTRODUCTION

Informed consent for any surgical intervention is necessary, as only well-informed patients can actively participate in the decision-making process about their care, and better understand the likely or potential outcomes of their treatment. No consensus exists on informed consent for suspension microlaryngoscopy (SML).

MATERIALS AND METHODS

Informed consent procedures in nine countries on five continents were studied.

RESULTS

Several risks can be discerned: risks of SML as procedure, anesthesiologic risks of SML, specific risks of phonosurgery, risks of inadequate glottic exposure or unexpected findings, risks of not treating. SML has recognized potential complications, that can be divided in temporary (minor) complications, and lasting (major) complications.

CONCLUSION

SML is a safe procedure with low morbidity, and virtually no mortality. Eleven recommendations are provided.
