- Abstract
The aim of this study was to investigate the efficacy of peritubular infiltration and ultrasound-guided low thoracal paravertebral block in patients undergoing percutaneous nephrolithotomy (PCNL). Sixty patients, American Society of Anesthesiologists I–II, between the ages of 18 and 65 years undergoing PCNL were randomized into three groups. Group peritubal infiltration (Pi, n = 20) received infiltration along the nephrostomy tube 20 ml 0.25% bupivacaine, in 6 and 12 o'clock position. Group paravertebral block (Pv, n = 20) received single-shot paravertebral block with 20 ml 0.25% bupivacaine at the level of T8–T9. Group control (C, n = 20): no intervention is performed. Postoperative opioid consumption and pain scores, opioid-related side effects, and additional analgesic requirement were recorded. The fentanyl consumption in Group Pv was significantly lower in comparison to Group C in all time intervals (p < 0.05). In the comparison of Group Pv and Group Pi, fentanyl consumptions in the postoperative 0–4th hours (100.00 ± 50.65 and 145.00 ± 61.55, respectively), 4–8th hours (50.00 ± 64.88 and 121.25 ± 56.93 respectively), and in the total of 24 h (197.50 ± 133.74 and 368.75 ± 116.66 respectively) were significantly lower in Group Pv (p < 0.05). The dynamic VAS scores analyzed at the 1st and 2nd hours were significantly lower in Group Pv than Group Pi (p < 0.05). Eight patients in Group C, two patients in Group Pi and 1 patient in Group Pv required additional analgesics and the difference was significant (p < 0.05). Paravertebral block achieved more effective analgesia by reducing postoperative opioid consumption and VAS scores comparison to the control and peritubal infiltration groups in patients undergoing percutaneous nephrolithotomy.
