Indication, complication, and prognosis of fiberoptic bronchoscopy guided percutaneous dilatation tracheostomy opening in respiratory intensive care unit: a retrospective study

OBJECTIVE

Percutaneous dilatational tracheostomy (PDT) is a bedside applicable procedure in intensive care unit patients requiring long-term mechanical ventilation. Fiber optic bronchoscopy (FOB) makes it easier and reduces complications. Our study aimed to evaluate the indications, complications, and prognosis of PDTs performed with FOB.

PATIENTS AND METHODS

Our study included 114 patients undergoing PDT through FOB-guided Griggs method in the Respiratory Intensive Care Unit between January 01, 2018, and January 31, 2023.

RESULTS

Among the patients undergoing PDT with FOB, 81 (71.1%) were male. The mean age was 62.1±11.5. The median Glasgow Coma Scale (GCS) score was 9, the median Acute Physiology and Chronic Health Evaluation-II (APACHE-II) score was 19, and the median Sequential Organ Failure Assessment (SOFA) score was 8. Tracheostomy was opened for prolonged mechanical-ventilator requirement in 80 patients (70.2%), to protect the airway in 19 (16.7%), and for poor neurologic status in 15 patients (13.2%). Complications during the procedure included hypoxemia in 3 patients (2.6%), minor bleeding in 3 patients (2.6%), perforation of the FOB in one patient (0.8%), and perforation of the intubation tube cuff in one patient (0.8%). 79 patients (69.3%) were discharged, and 35 (30.7%) were exited. There was a significant difference between the GCS, APACHE-II, and SOFA scores of the patients discharged and those who exited (p < 0.001).

CONCLUSIONS

FOB-guided PDT application should be encouraged as it reduces complications but it is still limited because it requires experienced specialists and equipment for a standard approach.

[From carbonmonoxide intoxication to organ donation; organ protective mechanic ventilation in severe pulmonary damage]

Organ donation is a matter of concern in critically ill patients who need intensive care after carbonmonoxide (CO) intoxication. A 26-year-old female patient was unconscious after having spent 20 minutes in the bathroom with a water heater (70% butane and 30% propane mixture). In the CT of the patient with Glasgow Coma Scale (GCS) 3, ventricular system was erased, white-gray matter separation was lost and fissures were observed as erased. Torax CT showed conspicuous areas showing air bronchograms in both lung bases and posterior areas and diffuse frosted glass densities in other areas. In a patient with no improvement in consciousness; apnea test, neurological examination and CT angiography showed that there was no blood flow in the brain and brain death was confirmed. On the second day of hospitalization, the relatives gave their approval for the donation. It may also be advantageous to use oxygen at high concentrations in carbonmonoxide poisoning as it may allow recruitment of closed alveoli. Successful kidney, heart, lung, liver and pancreas transplants from donors exposed to CO have been reported. Carbonmonoxide intoxication may be appropriate for transplantation for patients who are waiting for organs of brain death cases where the organ preservation is well done. Although carbonmonoxide intoxication has failed in the literature, it shows that there is no definite contraindication.

Management of Acute Respiratory Distress Syndrome with H1N1 Influenza Virus in Pregnancy: Successful Mechanical Ventilation and Weaning with Airway Pressure Release Ventilation

In pregnancy, infection with H1N1 influenza virus may produce symptoms similar to infection with seasonal influenza virus. Patients may rarely come with a clinical condition causing severe acute respiratory distress syndrome (ARDS) and death. Therefore, mechanical-ventilation strategies to manage these events are vital. We report a case of ARDS after an infection with H1N1 influenza A in a 33-year-old patient pregnant at 27-weeks. The ARDS was successfully managed by airway pressure release ventilation (APRV). APRV can be used successfully as an alternative to conventional mechanical ventilation modes in pregnant patients experiencing severe respiratory failure.
