Overview
Brief Summary
In this study, the investigators aimed to compare postanesthetic agitation in patients undergoing laparotomic gynecological surgery under general anesthesia using sevoflurane at a fresh gas flow rate of 2 L / min with fresh gas flow rate of 0.5 L / min.
Detailed Description
Emergence agitation is a temporary state of mental anxiety that occurs during general anesthesia recovery. It is characterized by emergence agitation, hallucination, excitation, delusion and confusion. Increased hemorrhage due to hypertension may cause serious complications such as injury to the surgical site, patients' self-removal of surgical drains and catheters, and self-extubation. Due to these, emergence agitation results need for additional treatment, psychological stress and increased medical workload for patients and their families. Emergence agitation after general anesthesia in adult patients was reported up to 20%. However, the ratios are very wide. In our operating room, the investigators observed that patients with low flow anesthesia were less agitated in the recovery phase than patients with normal flow anesthesia. In our researches, the investigators have not found any studies on the agitation values of patients who underwent low flow anesthesia in the literature.

Arms & Interventions
Postsurgical Pain
pain is defined as unpleasant sensation that can range from mild, localized discomfort to agony.
Intervention: Analgesics
Postanesthesia nausea and vomiting
nausea defined as feeling of sickness or discomfort in the stomach that may come with an urge to vomit.
Intervention: Antiemetics
Outcomes
Primary Outcomes
Postanesthetic emergence agitation
Time Frame: 30 minutes after general anesthesia recovery
Emergence agitation is a temporary state of mental anxiety that occurs during general anesthesia recovery. It is characterized by emergence agitation, hallucination, excitation, delusion and confusion. Emergence agitation is defined as the Riker sedation-agitation scale (SAS) score of 5 or more at any time in the PACU. Riker sedation-agitation scale: 7 point is 'Dangerous agitation' 6 point is 'very agitated' 5 point is 'agitated' 4 point is 'calm and cooperative' 3 point is 'sedated' 2 point is 'very sedated' 1 point is 'unarousable'
Secondary Outcomes
- postanesthetic nausea and vomiting(30 minutes after general anesthesia recovery)
