Evaluation of erector spinae plane block in patients undergoing percutaneous nephrolithotomy in terms of postoperative pain reduction and patient satisfaction.

OBJECTIVES: Intravenous opioids and local anesthetic infiltrations are traditionally used to relieve postoperative pain. With developments in the field of regional anesthesia, several methods are now available for postoperative analgesia. This study aimed to investigate the efficacy of the erector spinae plane block (ESPB) in reducing both intraoperative opioid consumption and postoperative analgesic use in patients undergoing percutaneous nephrolithotomy (PCNL). METHODS: A total of 60 patients who underwent PCNL were divided into two groups: 30 patients who received ESPB (Group I) and 30 patients in the control group (Group II). Intraoperative and postoperative opioid usage were recorded for both groups. The pain levels of the patients were evaluated using visual analog scale (VAS) scores obtained at 1, 3, 6, 12, and 24 hours postoperatively. Postoperative satisfaction of the patients in both groups was also questioned and compared. RESULTS: A significant difference was detected between Group I and Group II patients in terms of intraoperative opioid require-ments (p=0.00), analgesic requirements in the first 24 hours postoperatively (p=0.00), patient satisfaction status (p=0.00), and VAS scores obtained at 0, 3, 6, and 12 hours postoperatively. No significant difference was found in VAS scores at the 24th postoperative hour. CONCLUSION: ESPB is a simple, convenient technique that can be performed under ultrasound guidance. It provides remarkable postoperative analgesia and satisfaction in patients undergoing PCNL.

Comparison of the efficacy of five different objective methods to evaluate the success of infraclavicular block; which one of them is a reliable and early indicator?

BACKGROUND: Traditional methods that evaluate the success of peripheral nerve block have been replaced by methods that allow objective evaluations over time. Multiple objective techniques for peripheral nerve block have been discussed in the literature. This study aims to investigate whether perfusion index (PI), non-invasive tissue hemoglobin monitoring (SpHb), tissue oxygen saturation (StO2), tissue hemoglobin index (THI), and body temperature are reliable and objective methods to evaluate the adequacy of infracla-vicular blockage. METHODS: Ultrasound-guided infraclavicular block in 100 patients undergoing forearm surgery. PI, SpHb, StO2, THI, and body tem-perature measurements was recorded 5 min before the block procedure, right after the procedure, and until the 25th min after the procedure at 5-min intervals. These values were compared between the blocked limbs and non-blocked limbs while being statistically compared between the successful and failed block groups. RESULTS: Although there were significant differences between the groups of blocked extremity and non-blocked extremity in terms of StO2, THI, PI, and body temperature, there was no significant difference between these groups in terms of SpHb. Moreover, a sig-nificant difference was detected between the groups of successful block and failed block in terms of StO2, PI and body temperature, while there was no significant difference between these groups in terms of THI and SpHb. CONCLUSION: StO2, PI, and body temperature measurements are the simple, objective, and non-invasive techniques to be used to evaluate success of block procedures. According to the receiver operating characteristic analysis, StO2 is the specific parameter with the highest sensitivity among these parameters.

Ultrasound-guided bilateral infraclavicular brachial plexus block: A report of three cases.

Anesthesiologists avoid multiple upper extremity peripheral nerve block applications due to complications such as increased phrenic nerve palsy and local anesthetic systemic toxicity risk. With the introduction of ultrasound into clinical life and the increase in the number of experienced anesthesiologists, such complications are less common. We also discussed three cases that we think may contribute to the literature on this subject. Our first case was scheduled for operation due to a trigger finger in his left hand and carpal tunnel syndrome in his right hand. Our second case was scheduled for surgery due to distal radius and ulnar fractures in both forearms. Our third case scheduled for operation for a fracture of the right forearm distal radius and a second metacarpal fracture in the left hand. In this report series, we present our experience of bilateral infraclavicular block, which we successfully performed in three cases and did not encounter any complications.
