Risk factors for difficult ventilatory weaning in intensive care patients with cervical cellulitis

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Pulmonology

Background:

• Cervical cellulitis is a serious infection requiring mechanical ventilation.
• Difficult airway management and prolonged ventilation are common challenges.
• Identifying predictors for difficult ventilatory weaning is crucial for patient outcomes.

Purpose of the Study:

• To identify risk factors for difficult ventilatory weaning in intensive care unit (ICU) patients with cervical cellulitis.
• To explore factors associated with prolonged mechanical ventilation or extubation failure.

Main Methods:

• Retrospective observational study (January 2013 - December 2018) in a university hospital ICU.
• Included 120 patients with severe cervical cellulitis requiring mechanical ventilation.
• Defined difficult ventilatory weaning as mechanical ventilation >7 days or extubation failure (WIND 2017 criteria).

Main Results:

• A high procalcitonin level on ICU admission was a significant risk factor for difficult ventilatory weaning (OR 1.14).
• Surgery performed in an expert center was a protective factor (OR 0.11).
• 16% of patients had mediastinal extension; 8 patients required tracheotomy.

Conclusions:

• Procalcitonin levels and surgical center expertise are potential predictors for difficult ventilatory weaning in cervical cellulitis.
• Further multicenter prospective studies are needed to validate these findings.
• Simple criteria may help predict weaning difficulties in this patient population.
