“…The time interval for defining prolonged MV or extubation failure has yet to be established, ranging from 6 to 48 h in recent studies (6)(7)(8)(9) and from 2 to 7 days in older studies (10,11). The maintenance of patients on MV for a prolonged length of time can cause complications such as development of oxygen toxicity, larynx injuries, tracheal stenosis, selective intubation, sinusitis, barotrauma, reduced cardiac output, pneumonia, and psychological problems (12).…”

48 h) until discharge from the hospital or death. The occurrence of PPC, incidence of death, the need for reoperation and tracheostomy, and the length of hospitalization were assessed during the postoperative period. Twenty-six patients (8.2%) experienced extubation failure and 30 (9.5%) needed prolonged MV after surgery. Multivariate analysis showed that extubation failure was significant for the occurrence of death (OR = 8.05 [1.88; 34.36]), PPC (OR = 11.18 [2.27; 55.02]) and tracheostomy (OR = 7.8 [1.12; 55.07]). Prolonged MV was significant only for the occurrence of PPC (OR = 4.87 [1.3; 18.18]). Elective intracranial surgery patients who experienced extubation failure or required prolonged MV had a higher incidence of PPC, reoperation and tracheostomy and required a longer period of time in the ICU. Level of consciousness and extubation failure were associated with death and PPC. Patients who required prolonged MV had a higher incidence of extubation failure.]]>

“…Vidotto et al reported a 9.5 % incidence of prolonged mechanical ventilation and an 8.2 % incidence of extubation failure in patients admitted for elective intracranial surgery [9]. In a separate study of 92 patients undergoing intracranial surgery, Vidotto et al found that 16 % of patients required intubation within 48 h [10].…”

“…The decision regarding whether a patient can tolerate the removal of the orotracheal tube is crucial because both extubation delay and failure are associated with adverse effects and increased mortality. (4,8-12) Therefore, accurate knowledge of the risk factors and predictors of extubation failure is needed.…”

ObjectiveTo investigate the association between the rapid shallow breathing index and successful extubation in patients with traumatic brain injury. MethodsThis study was a prospective study conducted in patients with traumatic brain injury of both genders who underwent mechanical ventilation for at least two days and who passed a spontaneous breathing trial. The minute volume and respiratory rate were measured using a ventilometer, and the data were used to calculate the rapid shallow breathing index (respiratory rate/tidal volume). The dependent variable was the extubation outcome: reintubation after up to 48 hours (extubation failure) or not (extubation success). The independent variable was the rapid shallow breathing index measured after a successful spontaneous breathing trial. ResultsThe sample comprised 119 individuals, including 111 (93.3%) males. The average age of the sample was 35.0±12.9 years old. The average duration of mechanical ventilation was 8.1±3.6 days. A total of 104 (87.4%) participants achieved successful extubation. No association was found between the rapid shallow breathing index and extubation success. ConclusionThe rapid shallow breathing index was not associated with successful extubation in patients with traumatic brain injury.

The Prediction of Extubation Success of Postoperative Neurosurgical Patients Using Frequency–Tidal Volume Ratios

Abstract: The f/V (t) ratio does not predict extubation failure in patients who have undergone elective craniotomy. Patients who fail extubation present higher incidence of pneumonia, tracheostomy and higher mortality rate.
