Predicting postoperative tracheostomy requirement in children undergoing surgery for posterior fossa tumors

Incidence and Perioperative Risk Factors of Delayed Extubation following Pediatric Craniotomy for Intracranial Tumor: A 10-Year Retrospective Analysis in a Thailand Hospital

Background The determination of extubation (early or delayed) after pediatric craniotomy for intracranial tumor should be carefully considered because each has its pros and cons. The aim of this study was to investigate the incidence of the delayed extubation in these patients. The secondary goal was to identify the perioperative factors influencing the determination of delayed extubation.

Methods This retrospective study was performed in pediatric patients with intracranial tumor who underwent craniotomy at a university hospital between April 2010 and March 2020. Preoperative and intraoperative variables were examined. The variables were compared between the delayed extubation and early extubation group.

Results Forty-two of 286 pediatric patients were in the delayed extubation group with an incidence of 14.69%. According to multivariate analyses, the risk factors that prompted delayed extubation were the intracranial tumor size ≥ 55 mm (adjusted odds ratio [AOR], 2.338; 95% confidence interval [CI], 1.032–5.295; p = 0.042), estimated blood loss (EBL) ≥ 40% of calculated blood volume (AOR, 11.959; 95% CI, 3.457–41.377; p < 0.001), blood transfusion (AOR, 3.093; 95% CI, 1.069–8.951; p = 0.037), duration of surgery ≥ 300 minutes (AOR, 2.593; 95% CI, 1.099–6.120; p = 0.030), and completion of the operation after working hours (AOR, 13.832; 95% CI, 2.997–63.835; p = 0.001).

Conclusions The incidence of delayed extubation after pediatric craniotomy was 14.69%. The predictive factors were the size of tumor ≥ 55 mm, EBL ≥ 40% of calculated blood volume, blood transfusion, duration of surgery ≥ 300 minutes, and completion of surgery after routine working hours.

Tracheostomy practices in children on mechanical ventilation: a systematic review and meta-analysis

OBJECTIVE

To evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation.

SOURCE OF DATA

The authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using the Mantel-Haenszel method.

SYNTHESIS OF DATA

Sixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p = 0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p < 0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p < 0.008). For the days in PICU, the mean reduction was of 14.7 days (p < 0.007).

CONCLUSIONS

The meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation .

Predictive Factors for Postoperative Tracheostomy Requirement in Children Undergoing Surgical Resection of Medulloblastoma

OBJECTIVE

This study is aimed at identifying factors predicting tracheostomy requirement in children diagnosed with a posterior fossa medulloblastoma postoperatively.

METHODS

A retrospective chart review of all patients younger than 18 undergoing medulloblastoma resection from 2012 to 2020 at Namazi Hospital was conducted.

RESULTS

Forty-five patients (26%) needed tracheostomy after the operation. The most common correlates were brainstem compression and absence of gag reflex before operation. Patients who had brainstem compression and infiltration by medulloblastoma, bilateral absence of gag reflex before operation, subtotal resection of the tumor, and postoperative brainstem contusion were more likely to require tracheostomy. No statistically significant difference was observed between males and females and different ages.

CONCLUSIONS

Medulloblastoma is the most common pediatric malignancy. Postoperative ventilator dependency is an important complication in postoperative recovery of patients undergoing medulloblastoma resection. Considering the mutism syndrome with all its question marks by means of predisposing factors, we dealt with a 2-week policy whether there would be any clinical resolution regarding patients' gag reflex. The results show that if we aim for total tumor resection, tracheostomy that is a highly costly and stressful postoperative morbidity can be prevented.
