Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Conclusion

Although NPV by poncho-wrap ventilators appears to be a safe means to reduce the prevalence of hypoventilation during LT, the real usefulness of the association of NPV, general anesthesia, and manually assisted ventilation might be questioned considering the absence of relevant clinical complications in both groups. Nevertheless, compared to our prior method and that of […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Deliberation

In patients submitted for bronchoscopy and laser surgery of major tracheobronchial obstructions, Vourc’h et al compared jet ventilation and high-frequency jet ventilation. They demonstrated adequate and similar gas exchanges either with high-frequency jet ventilation or manual jet ventilation in patients with tracheal stenosis. The average duration of their sessions was 30 to 75 min. In […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Discussion

Several studies describe techniques of ventilation and anesthesia during LT or bronchoscopy: conventional mechanical ventilation through the bronchoscope, conventional or manual jet ventilation,  and spontaneous assisted ventilation. Most of these studies are uncontrolled or retrospective; no study is randomized. To the best of our knowledge, ours is the first prospective randomized controlled study to report […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Results

As shown in Table 1, there were no significant differences between the two groups as for demographic, anthropometric, and spirometric data, diagnoses of endobronchial lesions, and the anesthestic risk. The duration of the surgical procedure was similar in the two groups (46±12 min vs 49±21 min for NPV group and control group, respectively); the additional […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Measurement

Apnea Assessment: Time course of respiratory rate, tidal volume (Vt), Ve, number of apnea/hypopnea events (AHe) per patient, apnea/hypopnea index (AHI), and apnea/hypopnea duration (AHD) were assessed by means of evaluation of thoracic and abdominal movements using respiratory inductance plethysmography (RIP) (Respitrace Plus; Ambulatory Monitoring; Ard-sley, NY). Quantitative diagnostic calibration was done calibrating the sum […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Procedure

In case of prolonged apnea assessed clinically, and/or oxyhemoglobin desaturation (Sa02<88%), maximal oxygen supplementation was given, and ventilation was assisted manually until optimal saturation returned. At the end of the operation, patients were extubated when spontaneous ventilation had returned and awakening was imminent. Oxygen was administered by a nasal cannula and patients were moved to […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia: Materials and Methods

Study Population Twenty-seven consecutive patients underwent LT by means of rigid bronchoscopy because of tracheal or bronchial lesions. Demographic, anthropometric, associated conditions, diagnoses of endobronchial lesions, and the anesthetic risk of patients as assessed by means of the American Society of Anesthesiologists (ASA) risk classification are shown in Table 1. Most patients showed significant symptoms […]

Breathing Pattern and Arterial Blood Gases During Nd-YAG Laser Photoresection of Endobronchial Lesions Under General Anesthesia

Use of Negative Pressure Ventilation: A Preliminary Study Laser therapy (LT) has proved to be a very suitable procedure to treat endobronchial lesions, even in patients at very severe stages of diseases. Although the risk of general anesthesia is considered to be low, hypoxemia, hypercapnia, and acidosis secondary to apneas or reduction in ventilation are […]
