Gynecologic Cancer, Genitourinary Cancer
Conditions
Brief summary
This is a pilot study to determine if pulmonary function (lung compliance and ventilation/perfusion matching) is improved using APRV during general anesthesia, compared to the standard CMV. APRV will be tested during anesthesia in 12 patients undergoing robotic-assisted gynecological or genitourinary surgical procedures for definitive cancer treatment, who will also receive CMV.

Eligibility
Inclusion criteria
* Participants must have histologically or cytologically confirmed gynecological or genitourinary cancer. * Subjects will have the physiologic reserve to undergo a robotic-assisted gynecological or genitourinary surgical procedure that uses anesthesia via Airway Pressure Release Ventilation and via Conventional Mechanical Ventilation. * Adults (≥18 years old) * ECOG performance status ≤ 2. * Ability to understand and the willingness to sign a written informed consent document.
Exclusion criteria
* Vulnerable subjects will not be enrolled for this study. * Patients who have COPD and are on oxygen at home or who have COPD requiring routine daily inhalers or daytime oxygen are excluded. * Patients who have history of major lung resection are excluded. * Patients with body mass index (BMI) \>50 are excluded. * Patients with pulmonary infection within the past 2 months of screening are excluded. * The availability of oxygen to a fetus during this experimental procedure has not been established. Therefore, patients known to be pregnant per operating room (OR) policy will be excluded.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Optimal intra-operative ventilatory settings - Inspiratory Pressure | At surgery | Determination of the optimal intra-operative ventilatory settings for inspiratory pressure, expiratory pressure, inspiratory-expiratory time ratio and inspired oxygen concentration, that result in the best possible measured pulmonary function (i.e., compliance and gas exchange). |
