Fiberoptic bronchoscopic treatment of blood aspiration and use of sugammadex in a patient with epistaxis: A case report

Efficacy and airway complications of Parker Flex-Tip tubes and standard endotracheal tubes during airway manipulation: A meta-analysis and trial sequential analysis

BACKGROUND

Despite reported superior intubation outcomes associated with Parker Flex-Tip (PFT) tubes compared with those associated with standard polyvinylchloride tubes, the efficacy and safety of PFT tubes remain uncertain.

OBJECTIVES

To compare the intubation outcomes between PFT and conventional standard polyvinylchloride tubes.

DESIGN

Meta-analysis of randomised controlled trials.

DATA SOURCES

Embase, Medline, Google Scholar, PubMed and the Cochrane controlled trials register from inception until 3 January 2021.

ELIGIBILITY CRITERIA

All randomised trials comparing intubation outcomes between PFT (PFT group) and standard polyvinylchloride (standard polyvinylchloride group) tubes.

RESULTS

Analysis of the 13 eligible trials showed no significant difference in successful first-attempt intubation rate [risk ratio (RR) 1.20, 95% confidence interval (CI) 0.99 to 1.44] (6 trials, 568 participants), trauma risk (RR 0.83, 95% CI 0.67 to 1.03) (5 trials, 501 participants) as well as the overall risks of epistaxis (RR 0.58, 95% CI 0.26 to 1.31) (3 trials, 262 participants), sore throat (RR 0.90, 95% CI 0.70 to 1.17) (4 trials, 451 participants) and hoarseness (RR 0.71, 95% CI 0.44 to 1.14) (4 trials, 451 participants) between the two groups. However, the intubation time was slightly shorter (weighted mean difference -4.2 s, 95% CI -7.4 to -1.0 s) (8 trials, 759 participants) and the risks of severe epistaxis (RR 0.15, 95% CI 0.03 to 0.84) (3 trials, 262 participants) and overall difficulty in airway manipulation (RR 0.48, 95% CI 0.29 to 0.80) (8 trials, 647 participants) were lower in the PFT group than those in the standard polyvinylchloride group. Trial sequential analysis conclusively confirmed a shorter intubation time with PFT tubes than with standard polyvinylchloride tubes, whereas other intubation outcomes were inconclusive.

CONCLUSION

The use of PFT tubes for airway manipulation was associated with a shorter intubation time compared with the standard polyvinylchloride tubes. The results of trial sequential analysis suggest the need for further trials and meta-analysis to compare other intubation outcomes associated with the two devices.

Tracheal Irrigation Without Bronchoscopy as an Alternative Emergent Treatment of Blood Aspiration

BACKGROUND

Tracheobronchial foreign body aspiration can cause mild symptoms but may also become dangerous enough to cause death. Bronchoscopy is the first choice for the diagnosis and the removal of aspirated foreign bodies. So, when bronchoscopy is not available, the situation might get challenging.

CASE REPORT

A 62-year-old man was waiting for emergent surgery for traumatic epidural hematoma in the Emergency Department (ED). Endotracheal intubation was performed for surgery and airway maintenance. However, oxygen saturation dropped and respiratory arrest was expected. As emergent bronchoscopy could not be performed, the emergency physician decided to irrigate the trachea by using 0.9% normal saline in the ED. After three rounds of irrigation, vital signs including oxygen saturation improved and the patient could undergo neurosurgical surgery. The patient was subsequently discharged with improved health. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Bronchoscopy is the first choice for the treatment and diagnosis in cases of bronchial aspiration of blood, such as that caused by epistaxis. However, in emergency situations, such as deteriorating vital signs due to aspiration of life-threatening amounts of blood from epistaxis, using blind tracheal irrigation as an alternative tool when bronchoscopy is not available can help in achieving clinically acceptable results.
