Efficacy of Intercostal Nerve Block for Pain Control After Percutaneous Nephrolithotomy: A Systematic Review and Meta-Analysis

Effect of Intermittent Thoracic Paravertebral Block on Postoperative Nausea and Vomiting Following Thoracoscopic Radical Resection of the Lung Cancer: A Prospective Randomized Trial

Purpose

To explore the benefits of ultrasound-guided intermittent thoracic paravertebral block (TPVB) combined with intravenous analgesia (PCIA) in alleviating postoperative nausea and vomiting (PONV) during video-assisted thoracic surgery (VATS).

Patients and Methods

120 patients with lung carcinoma undergoing VATS were included and divided into three groups: group S (single TPVB+PCIA), group I (intermittent TPVB+PCIA), and group P (PCIA). The patients' NRS scores, postoperative hydromorphone hydrochloride consumption, and intramuscular injection of bucinnazine hydrochloride were recorded. The incidence of PONV and complications were documented.

Results

Compared with the group P, both group I and group S had significantly lower static NRS scores from 1-48 hours after the operation (P <0.05), and the dynamic NRS score of group I at the 1-48 hours after the operation were significantly decreased (P <0.05). Compared with the group P, the proportion of patients with PONV in group I was significantly lower (P <0.05), while there was no significant difference in group S. Moreover, the hospitalization period of patients in group I was significantly reduced compared with the other two groups (P <0.01), and the patient satisfaction was significantly increased compared with the group P (P <0.05).

Conclusion

Intermittent TPVB combined with PCIA can reduce the postoperative pain and the occurrence of PONV.

Comparison of efficacy of intercostal nerve block versus peritract infiltration with 0.25% bupivacaine in percutaneous nephrolithotomy: A prospective randomized clinical trial

Introduction

Postoperative pain following percutaneous nephrolithotomy (PCNL) adds to the morbidity of patients requiring additional analgesia. Various modalities of pain control techniques, such as intercostal nerve block (ICNB) and peritract infiltration (PTI), are being studied for better pain management. This study compares the efficacy of ICNB with PTI for postoperative pain management.

Methods

A double-blinded, prospective, randomized control study was conducted, in which 0.25% bupivacaine, either ICNB or PTI, was given at the puncture site at the end of PCNL. The primary outcome was a comparison of postoperative pain score measured with resting Visual analogue Scale (r-VAS) and dynamic VAS (D-VAS) recorded at 2 h, 4 h, 8 h, 10 h, 12 h, 24 h, and at discharge. Injection ketorolac was given as rescue analgesia. Secondary outcomes include time to first rescue analgesia and total analgesic requirement (TAR).

Results

Sixty patients were randomized into two equal groups with 63.3% male and 36.6% female, with a mean age of 37.25 ± 13.09 years. In Group ICNB, 24 (40%) and 6 (10%) patients and in Group PTI, 21 (35%) and 9 (15%) patients underwent standard and mini PCNL, respectively, in each group. All cases were PCNL doen in prone position. The mean R-VAS and D-VAS scores at 2, 4, 8, 12, 24, and 48 h were similar in both groups. The mean TAR was 56.84 ± 0.33.00 mg and 55.54 ± 0.29.64 mg of injection ketorolac in Group ICNB and PTI, respectively (P < 0.894). The time to first rescue analgesic demand were 7.11 ± 4.898 h and 6.25 ± 3.354 h (P < 0.527). Both the groups were comparable in terms of length of hospital stay, stone clearance rate, and complication rate.

Conclusion

The ICNB was as efficacious as PTI for postoperative pain control with 0.25% bupivacaine following PCNL.

Combined multiple regional anesthesia for microwave ablation of liver Tumors: Initial experience

OBJECTIVE

This study aims to assess the feasibility and safety of combined multiple regional anesthesia (CMRA) as a potential strategy to decrease pain and reliance on intravenous analgesics during and after ultrasound-guided microwave ablation (US-guided-MWA) of liver tumors.

METHODS

A cohort of 75 patients with a total of 99 liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were randomly allocated into three groups: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA. Evaluative parameters included the Numerical Rating Scale (NRS) scores, consumption of morphine, incidence of complications, and factors influencing perioperative pain.

RESULTS

All patients successfully underwent US-guided-MWA. The peak NRS scores for pain during ablation across the three groups were 2.36 ± 1.19, 3.28 ± 1.59, and 4.24 ± 1.42 respectively (P < 0.01), while the count of patients requiring morphine were 4/25, 8/25, and 13/25 respectively (P < 0.01). Postoperative NRS scores for the three groups at 4, 8, 12, 24, and 36-hour intervals demonstrated a pattern of initial increase followed by a decrease, with the order at each interval being: Group A < Group C < Group B. Factors associated with increased pain included larger tumor size, greater number of tumors, and longer procedure and ablation time (P < 0.05). No major complications were recorded across the three groups.

CONCLUSION

CMRA offers an effective and safe modality to manage pain during and after US-guided-MWA of liver tumors.

Evaluating outcomes of patient-centered enhanced recovery after surgery (ERAS) in percutaneous nephrolithotomy for staghorn stones: An initial experience

Objective

To evaluate the outcomes of patient-centered enhanced recovery after surgery (ERAS) in -percutaneous nephrolithotomy (PCNL) for staghorn stones.

Patients and methods

A retrospective analysis of 106 patients with staghorn calculi who underwent PCNL treatment at the Third Xiangya Hospital from October 01, 2018 to September 30, 2021 was performed. The patients were divided into the ERAS group (n = 56) and traditional group (n = 50). The ERAS program focused on a patient-centered concept, with elaboration on aspects, such as patient education, nutritional support, analgesia, body warming, early mobilization, nephrostomy tube removal, and strict follow-up.

Results

The total stone free rate and total complication rate were similar in both groups. The visual analogue scale (VAS) 6 h after surgery, ambulation off bed time, indwelling fistula time, indwelling catheter time, and postoperative hospital stays were lower in the ERAS group than in the traditional group (P < 0.05). The multiple session rate in the ERAS group (19, 28.57%) was lower than that in the traditional group (30, 60%) (P = 0.007). The 1-year stone recurrence rate in the ERAS group (7, 17.5%) was lower than that in the traditional group (14, 38.9%) (P = 0.037).

Conclusion

The patient-centered ERAS in PCNL for staghorn stones accelerated rehabilitation by relieving postoperative pain, shortening hospitalization time, accelerating early ambulation, and reducing multiple session rate and 1-year stone recurrence rate, which have socioeconomic benefits.

Use of Ultrasound-Guided Interfascial Plane Blocks in Anterior and Lateral Thoracic Wall Region as Safe Method for Patient Anesthesia and Analgesia: Review of Techniques and Approaches during COVID-19 Pandemic

Ultrasound-guided interfascial plane blocks performed on the anterior and lateral thoracic wall have become an important adjuvant method to general anesthesia and an independent method of local anesthesia and pain management. These procedures diminish the harmful effects of anesthesia on respiratory function and reduce the risk of phrenic nerve paralysis or iatrogenic pneumothorax. In postoperative pain management, interfascial plane blocks decrease the dosage of intravenous drugs, including opioids. They can also eliminate the complications associated with general anesthesia when used as the sole method of anesthesia for surgical procedures. The following procedures are classified as interfascial plane blocks of the anterior and lateral thoracic wall: pectoral nerve plane block (PECS), serratus anterior plane block (SAP), transversus thoracic muscle plane block (TTP), pectoral interfascial plane block (PIF), and intercostal nerve block (ICNB). These blocks are widely used in emergency medicine, oncologic surgery, general surgery, thoracic surgery, cardiac surgery, orthopedics, cardiology, nephrology, oncology, palliative medicine, and pain medicine. Regional blocks are effective for analgesic treatment, both as an anesthesia procedure for surgery on the anterior and lateral thoracic wall and as an analgesic therapy after trauma or other conditions that induce pain in this area. In the era of the COVID-19 pandemic, ultrasound-guided interfascial plane blocks are safe alternatives for anesthesia in patients with symptoms of respiratory distress related to SARS-CoV-2 and appear to reduce the risk of COVID-19 infection among medical personnel.

Risk factors for moderate-to-severe postoperative pain after percutaneous nephrolithotomy: a retrospective cohort study

Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure for removing renal calculi, while a large number of patients experience acute moderate-to-severe pain despite the analgesia provided. This study aimed to explore the risk factors for postoperative pain after PCNL, which may provide a novel perspective to refine the enhanced recovery after surgery (ERAS) program and to improve clinical outcomes. The clinical data of 331 patients who underwent PCNL in our hospital from September 2020 to February 2021 were retrospectively analyzed. The pain intensity was assessed every 4 h until 24 h post-surgery. According to the visual analog scale (VAS) score, patients were divided into two groups: mild or no pain group (VAS score, 0–3) and moderate-to-severe pain group (VAS score, 4–10). The pre-, peri-, and post-operative data were collected and analyzed. The indicators with statistically significant differences were selected, and multivariate logistic regression analysis was employed to determine the risk factors for postoperative pain after PCNL. Among 331 patients, 221 patients had moderate-to-severe pain and the incidence rate was 66.77%. Multivariate logistic regression analysis showed that the independent risk factors for moderate-to-severe pain after PCNL were the diameter of the renal calculus (odds ratio (OR) = 6.23, 95% confidence interval (CI) 2.50–15.56, P = 0.001), the number of renal calculi (OR = 15.892, 95% CI 7.721–32.711, P < 0.01), the presence of residual calculi (OR = 1.780, 95% CI 0.897–3.533, P = 0.01), and operation time (OR = 1.033, 95% CI 1.020–1.046, P < 0.01). The diameter of the renal calculus, the number of renal calculi, the presence of residual calculi, and operation time were significant predictors of postoperative pain after PCNL.
