Abstract

Background: Patients with head trauma need mechanical ventilation in order to protect airway and prevent complications. However, due to the lack of well-developed weaning protocols, weaning failure rate among them is high and hence, they may need mechanical ventilation and stay in hospital for long time, resulting in heavy costs on healthcare systems and high risk of death.
Objectives: The aim of the present study was to evaluate the effects of using the Persian weaning tool on patient outcomes among patients with head trauma under mechanical ventilation.
Methods: This clinical trial was conducted in 2018 on sixty patients with head trauma who were receiving mechanical ventilation in the intensive care unit of Shahid Rajaei Hospital, Qazvin, Iran. Participantswere randomly allocated to an intervention and a control group. Weaning from mechanical ventilation in these groups was performed using the Persian Weaning Tool and routine physiciandirected method, respectively. Groups were compared with each other concerning weaning outcomes through the Mann-Whitney U and the chi-square tests conducted using the SPSS software (version 23.0).
Results: Weaning success rate in the intervention group was significantly greater than the control group (83.3% vs. 56.6%; P = 0.024) and the length of hospital stay in the intervention group was significantly shorter than the control group (19.9 vs. 28.9 days; P = 0.05). However, there were no significant between-group differences concerning extubation success rate (80.0% vs. 63.3%; P = 0.252) and mechanical ventilation duration (7.5 vs. 8.7 days; P = 0.3).
Conclusions: The use of the Persian Weaning tool is effective in increasing weaning success rate and shortening hospital stay but has no significant effects on extubation success rate and mechanical ventilation duration. Specific weaning assessment tools and protocols need to be developed for patients with neurologic conditions.
