The Effect of Preemptive Pregabalin on Postoperative Pain and Respiratory Dynamics in Robotic Prostatectomy Operation.
The Effect of Preemptive Administration of Pregabalin on Postoperative Pain and Respiratory Dynamics in Patients Undergoing Surgery for Robotic Radical Prostatectomy.
The study aimed to investigate the impact of preemptive pregabalin on the postoperative pain severity and the requirement of analgesic drugs in patients undergoing robotic radical prostatectomy surgery as primary outcome.
Additionally, it examined the effect of pregabalin on early postoperative respiratory dynamics as secondary outcome.

Detailed Description
Our study will be conducted on a total of 90 patients after ethics committee approval and patient consent. In the prospective observational study, patients will be divided into two groups: those who received preoperative pregabalin and those who did not.
Group 1: those who did not take pregabalin (n:45) Group 2: those who took pregabalin (n:45) Procedure to be applied (interventions) Those who have received pregabalin treatment drink 150 mg of pregabalin with a small amount of water 2 hours before the surgical procedure. All patients receive standard general anesthesia in the operating room after standard hemodynamic monitoring, invasive arterial pressure and Bispectral Index (BIS) monitoring.
Afterwards, all patients receive standard anesthesia maintenance and are monitored in mechanical ventilation (volume-controlled mode), PEEP at 7-8 cmH20 and ETCO2 level at 30-35mmHg during the pneumoperitoneum period. During the pneumoperitoneum period, intra-abdominal pressure is kept within the range of 12-14 mmHg.
During robotic surgery, the standard 45-degree upright Trendelenburg position and perioperative restrictive fluid management are performed. For postoperative analgesia, 0.06 mg/kg morphine, 1 gram (g) paracetomol and 8 mg onasetron are administered iv to all patients 30 minutes before the end of the operation. At the end of surgery and after extubation, patients are taken from the recovery unit to the service in accordance with Aldrete criteria. In the service, all patients are given paracetamol 1g every 8 hours and tenoxicam 20 mg every 24 hours for pain treatment. Tramadol 1 mg/kg iv is administered as rescue analgesic to patients with a VAS score >4.
Recording Data Patients' age, gender, BMI, and comorbidities are recorded. Perioperative heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), BIS value, ETCO2, PaCO2 (arterial blood gas), PaO2/Fi02 and peak airway pressure (Ppeak), plateau pressure (Pplato). ) is recorded at the times specified below.
T0: 10th minute after anesthesia induction (supine position 00) T1: 10 minutes after the start of pneumoperitoneum (supine position 00) T2: 30 minutes after the upright Trendelenburg position (450) T3: At the end of pneumoperitoneum (supine position 00) T4: 30 minutes after extubation (recovery unit) The FEV1, FVC, FEV1/FVC values of all patients in the routine respiratory function test performed preoperatively and on the second postoperative day are recorded.
Operation time, Trendelenburg time, perioperative urine amount and general fluid balance are recorded.
Postoperative pain levels of all patients were 30 minutes and 6, 12, 24, 36 days after extubation. It is evaluated and recorded with VAS (Visual Analog Scale) between 0-10 at the 48th and 48th hours.
Analgesic medications administered postoperatively, time of first rescue analgesic (tramadol) administration, total tramadol consumption amount, presence of nausea-vomiting, dizziness, visual impairment, presence of upper airway problems, pulmonary and surgical complications are recorded.
