Comparison of Erector Spinae Plane Block and Intravenous Patient-controlled Analgesia in Percutaneous Nephrolithotomy

Comparison of Erector Spina Plane Block and Intravenous Patient-controlled Analgesia in Patients Undergoing Percutaneous Nephrolithotomy

The primary purpose of this study was to compare the effects of erector spinal plane block (ESP) and IV patient-controlled analgesia (PCA) performed to provide analgesia in percutaneous nephrolithotomy surgeries on visual analog skala (VAS), additional analgesia need, patient satisfaction and mobilization times.

ASA I-III patients aged 18-65 years who underwent percutaneous nephrolithotomy at Van Yüzüncü Yıl University Faculty of Medicine were included in the study. The patients were informed about the study during the preoperative evaluation. In the randomized single-blind closed-envelope study, 30 patients ineach group and a total of 60 patients were included. Standard general anesthesia procedure was applied to all patients. Standard general anesthesia procedure was applied to all patients. Perioperative hemodynamic monitoring was performed. In patients who underwent general anesthesia, after the surgical procedure was completed, after sterility was ensured for the ESP group while the patient was in the lateral position for the ESPB procedure, the linear 10-18 MHz USG probe (Esaote MyLab 30, Geneva, Italy) was placed between two transverse processes in the paramedian plane and increased from 1mg/kg to %1 at the T7 level. 20 ml of 0.5 bupivacaine (Buvasin®, Vem, Istanbul, Turkey) + 2% arrhythmic residual SF from 1mg/kg was administered. For patients in the PCA group, 200 mg of tramadol was placed in 100cc of 0.9% NaCl. Set to PCA device. A 50mg loading dose was administered 10 minutes before the patient was extubated. After extubating, a bolus dose of 20 mg was started, with a 30-minute lock-in time, and an infusion dose of 5mg/hour. The 4-hour maximum limit was set to 200 mg. VAS score, need for additional analgesia, patient satisfaction (Likert scale), mobilization times and vital signs were recorded at 30 minutes, p1, 3, 6 and 12 hours after the operation.

The patients weredivided in two groups. Thirty patients were assigned to each group. Standard general anesthesia procedure was applied to all patients. Perioperative hemodynamic monitoring was performed. Group ESP underwent an erector spina block after the surgical procedure. Intravenous patient-controlled analgesia with tramadol was applied to group PCA patients. VAS score, need for additional analgesia, patient satisfaction (Likert scale), mobilization times and vital signs were recorded at 30 minutes, 1th, 3th, 6th and 12th hours after the operation.

After the surgical procedure was completed in patients who underwent general anesthesia, the necessary sterility was provided for the ESPB procedure while the patient was in the lateral position. 1mg/kg 0.5% bupivacaine + 1mg/kg 2% lidocaine was drawn into the same syringe and the volume was completed to 20 ml with normal saline. A linear 10-18 MHz USG probe was placed at the thoracic 7 level (Esaote MyLab 30, Geneva, Italy) in the paramedian plane between two transverse processes. The prepared local anesthetic drug was administered under the guidance of USG.

For patients in the PCA group, 200 mg of tramadol was placed in 100cc of 0.9% NaCl. Set to PCA device. A 50mg loading dose was administered 10 minutes before the patient was extubated. After extubating, a bolus dose of 20 mg was started, with a 30-minute lock-in time, and an infusion dose of 5mg/hour. The 4-hour maximum limit was set to 200 mg.

Visual Analog Scale score were recorded at the post operative 30 minutes, 1st, 3rd, 6th and 12th hours after the operation. High VAS score was interpreted as severe pain in patients. When the VAS score was 4 and above, additional analgesic (15 mg/kg paracetamol) was given intravenously.

When the VAS score was 4 and above, 15 mg/kg paracetamol was given intravenously. Additional analgesic drug (Paracetamol) was recorded in milligrams.

Patient satisfaction was recorded using a Likert scale at the 30th minute, 1st, 3rd, 6th and 12th hours after the operation. Patient satisfaction was scored between 1 and 5 using a Likert scale at the 30th minute, 1st, 3rd, 6th and 12th hours postoperatively. 1 point not satisfied at all, 2 points dissatisfied, 3 points not sure, 4 points satisfied, 5 points very satisfied.

Mobilization status was checked and recorded at the 30th minute, 1st, 3rd, 6th and 12th hours after the surgery. We accepted the extubation time as the postoperative 0th hour. We determined the time when the patients started walking for the first time after the surgery accordingly.
