Nonintubated Versus Intubated Anesthesia in Video-assisted Thoracic Surgery

Comparative Study of Nonintubated Anesthesia With Laryngeal Mask Versus Intubated Anesthesia With Double Lumen Tube in Video-assisted Thoracic Surgery

The purpose of this study is to compare to the patients undergoing nonintubated general anesthesia with laryngeal mask and undergoing intubated general anesthesia with double-lumen endotracheal intubation in Video-assisted thoracic surgery (VATS).

Although general anesthesia with double-lumen intubation is generally mandatory for Video-assisted thoracic surgery procedures intubation with double lumen tube is related to several risks. Nonintubated general anesthesia with laryngeal mask in patients with spontaneous breathing may be an alternative choice for minor VATS procedures.

Inclusion Criteria:

• Patients undergoing elective minor VATS procedures will be enrolled the study

Exclusion Criteria:

• patients <18 years old,
• body mass index (BMI)>30 kg/m2,
• American Society Association (ASA) Class>3,

• bradycardia (heart rate (HR) <45 beats min1)
• atrioventricular block,
• hepatic or renal dysfunction,
• coagulopathy,
• asthma
• sleep apnea syndrome
