Obstructive shock due to tracheal perforation following long-term placement of a tracheostomy tube in a pediatric patient: a case report.

ABSTRACT:

Background

Tracheal perforation, although rare, is a known late complication of tracheostomy tube placement.

Case presentation

We present a 7-year-old boy with severe physical and mental disabilities under tracheostomy and long-term mechanical ventilation and steroid therapy who suddenly developed obstructive shock secondary to pneumomediastinum and pneumothorax. Prior bronchoscopy had shown the tip of the tracheostomy tube contacting the posterior tracheal wall, causing ulceration and subsequent tracheal perforation. The perforation was bridged using a cuffed tracheostomy tube, but the patient subsequently died of additional comorbidities.

Conclusions

Our experience suggests that tracheal perforation should be considered when pediatric patients with tracheostomy tubes suddenly develop hypotension.

Project description:BackgroundTracheostomy tube capping is a commonly used test to determine if the tracheostomy tube can be removed. The success of the capping trial depends on the patient's ability to maintain sufficient spontaneous breathing with an occluded tracheostomy tube. The impact of an occluded tracheotomy tube on airway resistance is currently unknown. The aim of this study was to investigate tracheal pressure during capping or stoma button insertion and potential determinants concerning cuff.MethodsEight cuffed and uncuffed tracheostomy tubes and three stoma buttons of various manufacturers and sizes were inserted into the trachea model. Cuffs were completely deflated or contained atmospheric pressure. The trachea was ventilated bidirectional with a respirator in volume-controlled mode and volume flows 15-60 L/min. Tracheal pressure drop during inspiration as a parameter of pressure required to move gas through the airway was measured.ResultsTracheal pressure drops occurred linearly or irregularly during capping trials to a maximum of 4.2 kPa at flow rates of 60 L/min for atmospheric pressure cuffs. In tracheostomy tubes with completely deflated cuffs, pressure drop in the trachea reaches a maximum of 3.4 kPa at a flow rate of 60 L/min. For tracheostomy tubes with cuff smaller inner or outer diameters do not regularly result in lower tracheal pressure drop. The pressure drop varies between different tracheostomy tubes depending on the manufacturer. In cuffed tracheostomy tubes, we observed three phenomena: sail-like positioning, folding over, and tightening of the cuff during flow. The maximum tracheal pressure drop during stoma button insertion reaches 0.014 kPa.ConclusionsThe cuff is a central element for the pressure drop in the airway and thus airway resistance during spontaneous translaryngeal breathing with a capped TT. Complete deflation reduces the pressure drop in the trachea. Due to deformation of the cuff, measured pressures are irregular as the volume flow is increased. Incomplete deflated cuffs and material characteristics of tracheostomy tubes and cuffs in addition to anatomical and clinical variables may cause unsuccessful capping trials due to increased airway resistance. All stoma buttons showed that pressure drop and thus airway resistance due to stoma buttons has no clinical relevance.

Project description:BackgroundKetorolac-refractory pain behavior following bilateral myringotomy and pressure equalization tube placement (BMT) is associated with the absence of middle ear fluid. Intraoperative fentanyl/ketorolac affords more reliable pain control than ketorolac alone. We hypothesized that middle ear condition would correlate with postoperative pain despite such combination therapy. We further sought to demonstrate seasonal variation in ear condition and its influence on pain.MethodsWe conducted a single-institution retrospective cohort study of healthy children (9 months-7 years), who underwent BMT by a single surgeon from 2015 to 2020. Anesthetic care included sevoflurane/nitrous oxide/oxygen/air by mask and intramuscular fentanyl/ketorolac. Left/right middle ear fluid status was recorded at the time of BMT, and ear condition (primary exposure) was dichotomized as bilateral infected (mucoid or purulent) or normal/unilateral infected. The primary outcome was maximum postanesthesia care unit Face, Legs, Activity, Cry, and Consolability (FLACC) score: 4-10 (moderate-to-severe pain) versus 0-3 (no-to-low pain). Rescue oxycodone, acetaminophen administration, and emergence agitation were secondary outcomes. Statistical analysis incorporated generalized linear mixed-effect models (GLMMs) with random intercepts to account for clustering by anesthesia provider. A year-over-year monthly time-series analysis was conducted using an autoregressive integrated moving average (ARIMA) regression model.ResultsExcluding recurrent cases, 1149 unique evaluable subjects remained. Bilateral infection prevalence was 39.8% (457/1149; 95% confidence interval [CI], 37.0-42.6). Probability of moderate-to-severe pain behavior was 23.5% (270/1149; 95% CI, 21.1-26.0) overall. Compared to patients with bilateral infected middle ears, those with normal/unilateral infected ears were more likely to have a FLACC score ≥4 (26.7% [185/692] versus 18.6% [85/457]; odds ratio [95% CI], 1.7 [1.2-2.3]; P = .002). Variability in pain outcome explained by the multivariable GLMM was 4.7%. Fentanyl dose response was evidenced by oxycodone administration differences ( P ≤ 0.002). Moderate-to-severe pain and emergence agitation were more likely with reduced fentanyl dosing. Bilateral infection prevalence exhibited seasonality, peaking in March and nadiring in July. However, pain outcomes did not vary by season.ConclusionsNormal/unilateral infected ears at time of pediatric BMT are associated with higher incidence of moderate-to-severe postoperative pain following intraoperative fentanyl/ketorolac administration, but the predictive value of ear condition on pain is limited. Infections were less common in the summer.

Project description:The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease it causes (COVID-19) have resulted in an increase in critical illness and in the prevalence of acute respiratory failure with the need for tracheostomy. The characteristics and long-term outcomes of this patient cohort are not well identified.Research questionWhat are the characteristics of patients who develop the need for tracheostomy due to SARS-CoV-2 with acute respiratory distress syndrome (ARDS)? What is their 90-day and 1-year survival and are there any identifiable risk factors for mortality and ventilator dependency?Study design and methodsRetrospective, follow-up cohort study of adult patients with COVID-19 infection and ARDS who required tracheostomy placement in a large healthcare system.ResultsOne hundred sixty-four consecutive patients with SARS-CoV-2 admitted to ICUs for ARDS who required tracheostomy placement between March 2020 and March 2021 were identified. One hundred nine (66.5%) were male. Average age was 63.5 years. The most common comorbidities were obesity, hypertension, diabetes mellitus, congestive heart failure, chronic kidney disease, chronic obstructive pulmonary disease (COPD), atrial fibrillation, and asthma. The most common complications during hospitalization were delirium, secondary infections, acute kidney injury, pneumothorax, and venous thromboembolism. Ninety-day and 1-year mortality were 29.9% and 44.5%, respectively. Ninety-six patients (58.5%) were liberated from the ventilator, and 84 (51.2%) had the tracheostomy tube decannulated. Asthma, COPD, atrial fibrillation, and renal replacement therapy requirement in the ICU correlated with increased risk of ventilator dependency. Among survivors at 1 year, 71 patients (43.3%) were residing at home and 20 patients (12.2%) remained in a skilled nursing facility.InterpretationCOVID-19 has resulted in a significant burden of acute critical illness and acute respiratory failure with the need for tracheostomy. A significant percentage of patients with SARS-CoV-2 requiring tracheostomy were alive and at home 1 year after tracheostomy placement. Long-term care support, including tracheostomy, beyond 90 days appears to be beneficial in this patient population and warrants further investigation.

Project description:PurposeDespite the brevity of the procedure, bilateral myringotomy and tympanostomy tube placement (BMT) can result in significant postoperative pain and discomfort. As the procedure is frequently performed without intravenous access, non-parenteral routes of administration are frequently used for analgesia. The current study prospectively compares the efficacy of intranasal (IN) dexmedetomidine with IN fentanyl for children undergoing BMT.MethodsThis prospective, double-blinded, randomized clinical trial included pediatric patients undergoing BMT. The patients were randomized to receive either IN dexmedetomidine (1 μg/kg) or fentanyl (2 μg/kg) after the induction of general anesthesia with sevoflurane. All patients received rectal acetaminophen (40 mg/kg) and the first 50 patients also received premedication with oral midazolam. Postoperative pain and recovery were assessed using pediatric pain and recovery scales, and any adverse effects were monitored for.ResultsThe study cohort included 100 patients who ranged in age from 1 to 7.7 years and in weight from 8.6 to 37.4 kg. They were divided into 4 groups with 25 patients in each group: (1) midazolam premedication+IN dexmedetomidine; (2) midazolam premedication+IN fentanyl; (3) no premedication+IN dexmedetomidine; and (4) no premedication+IN fentanyl. Pain scores were comparable when comparing groups 2, 3 and 4, but were higher in group 1 (midazolam premedication with IN dexmedetomidine). There was no difference in total time in the post-anesthesia care unit (PACU) or time from arrival in the PACU until hospital discharge between the 4 groups. The heart rate (HR) was significantly lower in group 3 when compared to the other groups at several different times after arrival to the PACU. No clinically significant difference was noted in blood pressure.ConclusionFollowing BMT, when no premedication is administered, there was no clinical advantage when comparing IN dexmedetomidine (1 μg/kg) to IN fentanyl (2 μg/kg). The addition of oral midazolam as a premedication worsened the outcome measures particularly for children receiving IN dexmedetomidine.
