Effect of ultrasound-guided phrenic nerve block on shoulder pain after laparoscopic cholecystectomy—a prospective, randomized controlled trial

Post-laparoscopic Shoulder Pain Management: A Narrative Review

PURPOSE OF REVIEW

Post-laparoscopic shoulder pain (PLSP) can slow patient recovery and extend hospital stays, making its management crucial for patients undergoing laparoscopic surgery. Current consensus guidelines say little about how to prevent or manage PLSP. In this context, a multimodal approach to PLSP management that maybe extend beyond the pharmaceutical interventions currently employed. A variety of devices comprising both invasive and noninvasive approaches are available to patients, serving as adjuvants to analgesics. In this review, we explore the potential causes of PLSP. Additionally, by searching relevant databases and reviewing existing literature, we provide a comprehensive summary of current PLSP management strategies excluding analgesics.

RECENT FINDINGS

A total of 30 articles were reviewed. The review identified a number of different treatments for PLSP, including trendelenburg position, discharge of residual gas, pulmonary recruitment manoeuvre, low-pressure pneumoperitoneum and phrenic nerve block, among others. However, the inconsistencies in the study designs resulted in disparate conclusions. While the current studies provide valuable insights, there is a clear need for further research in this area.

The effect of lung-recruitment maneuver on postoperative shoulder pain in patients undergoing laparoscopic cholecystectomy: a randomized controlled trial

PURPOSE

Lung-recruitment maneuvers (LRM) have been shown to reduce postoperative pain after laparoscopic surgery. This study aimed to investigate the association of LRM with the incidence of shoulder pain after laparoscopic cholecystectomy.

METHODS

A randomized controlled study was conducted with 110 patients undergoing elective laparoscopic cholecystectomy from July 2022 to March 2023. Participants were randomized to receive either routine exsufflation or LRM at pneumoperitoneum release. The postoperative shoulder pain and abdominal pain were assessed at 1, 4, 6, 12, and 24 h after surgery using a numeric rating scale. Analgesic consumption and postoperative nausea or vomiting (PONV) were evaluated during the first 24 h after surgery.

RESULTS

The incidence of shoulder pain during the first 24 h after surgery was significantly lower in the LRM group compared to the control group (26.9 vs. 59.3%; P = 0.001). The median [interquartile range] score of worst shoulder pain was significantly lower compared to the control group (3 [2-3] vs 4 [3-5.5]; P = 0.003). Participants in the LRM group showed reduced abdominal pain at rest at 4 and 24 h after surgery, and experienced significantly lower intensities of abdominal pain during mobilization at all time points over 24 h after surgery. There were no significant differences in opioid consumption or the incidence of PONV between the groups.

CONCLUSIONS

LRM reduces both the incidence and intensity of shoulder pain during 24 h after laparoscopic cholecystectomy. Additionally, LRM was associated with reduced intensity of abdominal pain during mobilization over the study period.

Efficacy of Ultrasound-Guided Interscalene Brachial Plexus Block for Acute Post-Hepatectomy Shoulder Pain: A Randomized Controlled Trial

Objective

To investigate the efficacy of ultrasound-guided interscalene brachial plexus block in the treatment of shoulder pain following hepatectomy.

Design

A randomized controlled trial.

Methods

We conducted a single-center, randomized controlled trial. Forty-four patients with shoulder pain scores of at least 5 were randomly assigned to two groups: the treatment group, which received 0.5% ropivacaine (5mL) combined with dexamethasone (5 mg) (n=22), and the control group, which received normal saline (5mL) (n=22). The intervention was performed in the postanesthesia care unit after shoulder pain was identified by using the visual analogue scale. The shoulder pain was re-evaluated 15 minutes after intervention. The incidence of effective pain relief, defined as at least 75% reduction in pain intensity, was the primary outcome. Secondary outcomes included shoulder pain intensity within 2 days after surgery, the timing of the first rescue analgesia, total additional analgesic use, arterial oxygen saturation, intervention-related adverse reactions, and patient satisfaction regarding shoulder pain.

Results

The incidence of effective pain relief was significantly higher in the treatment group compared to the control group (15 (68.2%) vs 2 (9.1%), P<0.001). The interscalene brachial plexus block not only prolonged the time to first analgesic request (P <0.001), but also reduced the number of analgesic requests (P <0.001). In the comparison between groups, arterial oxygen saturation was lower in the control group than that in the treatment group, attributed to the use of sufentanil for remedial analgesia (92.4% vs 94.5%, P=0.014).

Conclusion

Interscalene brachial plexus block can effectively relieve post-hepatectomy shoulder pain without clinically significant hypoxemia.

Subdiaphragmatic phrenic nerve supply: A systematic review

OBJECTIVE

The aim of this systematic review is to study the subdiaphragmatic anatomy of the phrenic nerve.

MATERIALS AND METHODS

A computerised systematic search of the Web of Science database was conducted. The key terms used were phrenic nerve, subdiaphragmat*, esophag*, liver, stomach, pancre*, duoden*, intestin*, bowel, gangli*, biliar*, Oddi, gallbladder, peritone*, spleen, splenic, hepat*, Glisson, falciform, coronary ligament, kidney, suprarenal, and adrenal. The 'cited-by' articles were also reviewed to ensure that all appropriate studies were included.

RESULTS

A total of one thousand three hundred and thirty articles were found, of which eighteen met the inclusion and exclusion criteria. The Quality Appraisal for Cadaveric Studies scale revealed substantial to excellent methodological quality of human studies, while a modified version of the Systematic Review Centre for Laboratory Animal Experimentation Risk of Bias Tool denoted poor methodological quality of animal studies. According to human studies, phrenic supply has been demonstrated for the gastro-esophageal junction, stomach, celiac ganglia, liver and its coronary ligament, inferior vena cava, gallbladder and adrenal glands, with half of the human samples studied presenting phrenic nerve connections with any subdiaphragmatic structure.

CONCLUSIONS

This review provides the first systematic evidence of subdiaphragmatic phrenic nerve supply and connections. This is of interest to professionals who care for people suffering from neck and shoulder pain, as well as patients with peridiaphragmatic disorders or hiccups. However, there are controversies about the autonomic or sensory nature of this supply.

Effectiveness of Different Noninvasive Physiotherapy in Relieving Postlaparoscopic Shoulder pain: A Protocol for Systematic Review and Network Meta-Analysis

Background

Shoulder pain is one of the most common symptoms after laparoscopic surgery, which seriously affects people's health and quality of life. Many clinical studies have shown that noninvasive physiotherapy is the most beneficial treatment for patients, but the best approach for various noninvasive physiotherapy is unclear. The purpose of this study protocol is to compare the effectiveness of different noninvasive physiotherapy in relieving postlaparoscopic shoulder pain (PLSP).

Methods

We will search ten electronic databases including PubMed, Web of Science, Medline, Scopus, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), CNKI, WanFang Data and VIP databases from their inception to November 2023. We will select randomized controlled trials (RCTs) to evaluate the effectiveness of noninvasive physiotherapy on PLSP. Our primary outcome will be to measure the intensity of shoulder pain at 24 and 48 hours after the end of the noninvasive intervention in the included study. Secondary outcomes include incidence of shoulder pain at 24 and 48 hours, postoperative nausea / vomiting and incidence of other complications after noninvasive intervention. Then, standard network meta-analysis will be conducted using Review Manager 5.4 and STATA 18.

Results

Our systematic review and network meta-analysis will identify the best noninvasive physiotherapy for PLSP patients.

Conclusion

This systematic review will address the existing knowledge gap regarding best practice for relieving PLSP with noninvasive physiotherapy. The results of this network meta-analysis will help medical staff and patients choose the best method to relieve the PLSP. Furthermore, we hope that the results of this study will provide evidence-based for the improvement of guidelines and facilitate the decision sharing process.

Regional anaesthesia for postoperative pain management following laparoscopic, visceral, non-oncological surgery a systematic review and meta-analysis

BACKGROUND

Postoperative pain management following laparoscopic, non-oncological visceral surgery in adults is challenging. Regional anaesthesia could be a promising component in multimodal pain management.

METHODS

We performed a systematic review and meta-analysis with GRADE assessment. Primary outcomes were postoperative acute pain intensity at rest/during movement after 24 h, the number of patients with block-related adverse events and the number of patients with postoperative paralytic ileus.

RESULTS

82 trials were included. Peripheral regional anaesthesia combined with general anaesthesia versus general anaesthesia may result in a slight reduction of pain intensity at rest at 24 h (mean difference (MD) - 0.72 points; 95% confidence interval (CI) - 0.91 to - 0.54; I2 = 97%; low-certainty evidence), which was not clinically relevant. The evidence is very uncertain regarding the effect on pain intensity during activity at 24 h (MD -0.8 points; 95%CI - 1.17 to - 0.42; I2 = 99%; very low-certainty evidence) and on the incidence of block-related adverse events. In contrast, neuraxial regional analgesia combined with general anaesthesia (versus general anaesthesia) may reduce postoperative pain intensity at rest in a clinical relevant matter (MD - 1.19 points; 95%CI - 1.99 to - 0.39; I2 = 97%; low-certainty evidence), but the effect is uncertain during activity (MD - 1.13 points; 95%CI - 2.31 to 0.06; I2 = 95%; very low-certainty evidence). There is uncertain evidence, that neuraxial regional analgesia combined with general anaesthesia (versus general anaesthesia) increases the risk for block-related adverse events (relative risk (RR) 5.11; 95%CI 1.13 to 23.03; I2 = 0%; very low-certainty evidence).

CONCLUSION

This meta-analysis confirms that regional anaesthesia might be an important part of multimodal postoperative analgesia in laparoscopic visceral surgery, e.g. in patients at risk for severe postoperative pain, and with large differences between surgical procedures and settings. Further research is required to evaluate the use of adjuvants and the additional benefit of regional anaesthesia in ERAS programmes.

Research hotspots and trends in postlaparoscopic shoulder pain from 2003 to 2023: A bibliometric analysis

The incidence of postlaparoscopic shoulder pain has recently increased and has attracted increasing attention from clinical workers, but no study has performed bibliometric and visual analysis of the relevant literature. This study used bibliometric and visual analysis to conduct a comprehensive and systematic evaluation of postlaparoscopic shoulder pain to help researchers understand the latest global trends and hotspots and provide a reference for caregivers to carry out PLSP care interventions and research. Related studies on postlaparoscopic shoulder pain from 2003 to 2023 were retrieved from the Web of Science Core Collection. We analysed current research trends and hotspots in this field using VOSviewer and CiteSpace. A total of 2451 authors from 352 institutions in 50 countries published 464 studies related to postlaparoscopic shoulder pain. The United States was the country with the most publications and worked closely with other countries. Donmez Turgut was the researcher with the most published articles, while Bisgaard T had the most citations per article. The Journal of Surgical Endoscopy was cited most frequently, totalling 356 times. Through keyword significance analysis, we found that relieving postlaparoscopic shoulder pain in patients through integrated care interventions was an emerging research hotspot. This bibliometric and visual analysis provides a comprehensive review of studies related to postlaparoscopic shoulder pain. The current global research trend and hotspot is to alleviate postlaparoscopic shoulder pain through integrated care interventions, but the advantages of this approach are not outstanding. However, further research and global collaboration are still needed. Our findings can help researchers understand the current status of postlaparoscopic shoulder pain research and identify new directions for future research.

Influence of extent of surgical resection on post-hepatectomy shoulder pain: an observational study

Shoulder pain frequently follows hepatectomy. However, the influence of surgical procedures on shoulder pain is unclear. In this observational study, patients who underwent hepatectomy were enrolled in Shanghai Cancer Center. Shoulder pain and surgical pain were assessed using the numeric rating scale 2 days after surgery. The incidence of shoulder pain was the outcome of the cohort study. Nested case-control analyses were further applied. Three hundred and twelve patients were finally enrolled in this study. Nested case-control analysis showed that there were no significant differences in the number of surgical segments between the two groups (P = 0.09). In addition, minor hepatectomy did not reduce the incidence of shoulder pain compared with major hepatectomy (P = 0.37). The drainage volume within 2 days after surgery was significantly more in those patients with shoulder pain (P = 0.017). In open surgery, surgical sites involving the right anterior lobe (OR (95% CI) 2.021 (1.075, 3.802), P = 0.029) and right posterior lobe (OR (95% CI) 2.322 (1.193, 4.522), P = 0.013) were both independent risk factors for shoulder pain. Left shoulder pain also occurred in patients who did not receive left lateral hepatectomy. The preventive phrenic nerve block was not suitable for post-hepatectomy shoulder pain. Stronger preventative intervention should be used in those high-risk patients.

Pulmonary recruitment maneuver reduces the intensity of post-laparoscopic shoulder pain: a systematic review and meta-analysis

BACKGROUND

Post-laparoscopic shoulder pain (PLSP) is a common complication following laparoscopic surgeries. This meta-analysis aimed to investigate whether pulmonary recruitment maneuver (PRM) was beneficial to alleviated shoulder pain after laparoscopic procedures.

METHODS

We reviewed existing literature in the electronic database from the date of inception to January 31, 2022. The relevant RCTs were independently selected by two authors, after which data extraction, assessment of the risk of bias, and comparison of results.

RESULTS

This meta-analysis included 14 studies involving 1504 patients, among which 607 patients were offered pulmonary recruitment maneuver (PRM) alone or in combination with intraperitoneal saline instillation (IPSI), while 573 patients were treated with passive abdominal compression. The administration of PRM significantly decreased the post-laparoscopic shoulder pain score at 12 h (MD (95%CI) - 1.12(-1.57, - 0.66), n = 801, P < 0.001, I² = 88%); 24 h (MD (95%CI) - 1.45(-1.74, - 1.16), n = 1180, P < 0.001, I² = 78%) and at 48 h (MD (95%CI) - 0.97(-1.57, - 0.36), n = 780, P < 0.001, I² = 85%). We observed high heterogeneity in the study and analyzed the sensitivity but failed to identify the cause of the heterogeneity, which may have resulted from the different methodologies and clinical factors in the included studies.

CONCLUSION

This systematic review and meta-analysis indicate that PRM can reduce the intensity of PLSP. More studies may be needed to explore the usefulness of PRM in more laparoscopic operations besides gynecological surgeries and determine the optimal pressure of PRM or its appropriate combination with other measures. The results of this meta-analysis should be interpreted with caution owing to the high heterogeneity between the analyzed studies.

The effect of ultrasound-guided transversus abdominis plane block on pulmonary function in patients undergoing laparoscopic cholecystectomy: a prospective randomized study

BACKGROUND

Transversus abdominis plane block (TAPB) is commonly used for postoperative pain control after laparoscopic cholecystectomy. However, few studies have analyzed its effect on pulmonary function. The goal of this study was to elucidate the effect of ultrasound-guided bilateral TAPB on pulmonary function preservation and analgesia after laparoscopic cholecystectomy.

METHODS

We enrolled 58 patients who underwent laparoscopic cholecystectomy. Among them, 53 were randomized to group T (n = 27) and group C (n = 26). Group T and group C received ultrasound-guided bilateral TAPB with 40 ml of 0.375% ropivacaine and 40 ml of 0.9% normal saline, respectively. Visual analog scale (VAS) scores, patient-controlled analgesia (PCA) consumption, forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow rate (PEF), and modified Borg scale scores were measured until 24 h post-surgery.

RESULTS

The VAS scores were significantly lower in group T than in group C at 1 and 8 h after the surgery. PCA consumption was significantly lower in group T than in group C at all postoperative time points. FEV1, PEF, and FEV1/FVC were more preserved in group T than in group C at 1 h. Group T had significantly lower modified Borg scale scores than did group C at 1 and 8 h.

CONCLUSION

Ultrasound-guided TAPB is effective in pulmonary function preservation and pain control after laparoscopic cholecystectomy. Therefore, it could be a great option for multimodal analgesia, preservation of pulmonary function, prevention of pulmonary complications including atelectasis, and promotion of postoperative recovery after laparoscopic cholecystectomy.

Sodium Bicarbonate Sub-Diaphragmatic Irrigation Relieves Shoulder Pain After Total Laparoscopic Hysterectomy: A Randomized Controlled Trial

Study Objective

To determine whether sub-diaphragmatic irrigation with sodium bicarbonate would relieve post-laparoscopic shoulder pain (PLSP) after total laparoscopic hysterectomy.

Design

Randomized double-blinded trial.

Setting

Teaching hospital.

Patients

Seventy patients undergoing total laparoscopic hysterectomy (TLH) for benign indications.

Intervention

We randomly allocated patients to intervention or control groups where sodium bicarbonate containing flushing liquid or normal saline was irrigated sub-diaphragm before sewing.

Measurement & Main Results

The primary outcome was PLSP following surgery measured by a numerical rating scale (NRS) (0 = no pain; 10 = worst pain imaginable). Secondary outcomes were abdominal incisional and visceral pain, analgesic use, and sodium bicarbonate related side effects. The incidence of PLSP in intervention group was significantly lower than that in control group (P < 0.05). Contrarily, incisional and visceral pain was similar in both groups (P = 0.1). The consumption of rescue analgesics in the intervention group was lower than that in the control group. Side effects were comparable in both study groups.

Conclusion

Sub-diaphragmatic irrigation with sodium bicarbonate could effectively reduce shoulder pain, but not abdominal incisional and visceral pain, in patients undergoing TLH without an increase in side effects.

Phrenic nerve block on severe post-hepatectomy shoulder pain: A randomized, double-blind, placebo-controlled, pilot study

BACKGROUND

Severe shoulder pain occurs frequently after surgery close to the diaphragm, potentially caused by referred pain via the ipsilateral phrenic nerve. We aimed to assess the analgesic effect of an ultrasound-guided phrenic nerve block on moderate to severe right-sided shoulder pain after open partial hepatectomy.

METHODS

This was a randomized, double-blind, placebo-controlled, pilot study, comparing ultrasound-guided phrenic nerve block (ropivacaine 0.75 mg/mL) versus placebo (isotonic sodium chloride 0.9 mg/mL) on severe post-hepatectomy shoulder pain (NRS ≥6). Pre- and postoperative spirometry and arterial blood gas analyses were used to assess respiratory function. Subjects with chronic lung disease were excluded. Unfortunately, due to lack of funding, the trial was ended prematurely and therefore presented as a pilot study.

RESULTS

One hundred and one subjects were screened for eligibility; 14 subjects were randomized, and two subjects were later excluded; thus, 12 subjects were analyzed with six in each group. A statistically significant difference in reduction in median pain intensity between groups was observed 15 minutes after phrenic nerve block ("ropivacaine first" ΔNRS: -6.0 [-6.0 to -3.0] vs. "saline first" ΔNRS: 0 [-6.0 to 1.0], P = .026). Spirometry results and arterial blood gas analyses were not clinically impacted by the block.

CONCLUSIONS

Postoperative phrenic nerve block significantly reduced severe post-hepatectomy shoulder pain. Larger studies are warranted to confirm the lack of clinically relevant block-related impairment of respiratory function.

Novel Regional Nerve Blocks in Clinical Practice: Evolving Techniques for Pain Management

This review examines the use of novel US-guided nerve blocks in clinical practice. Erector spinae block is a regional anesthesia technique doing by injecting a local anesthetic among the erector spinae muscle group and transverse processes. The phrenic nerve is a branch of the cervical plexus, arising from the anterior rami of cervical nerves C3, C4, and C5. The quadratus lumborum muscle is located along the posterior abdominal wall. It originates from the transverse process of the L5 vertebral body, the iliolumbar ligament, and the iliac crest. US-guided peripheral nerve procedures have a considerable scope of use, including treating headaches and hiccups to abdominal surgical pain, cesarean sections, musculoskeletal pathologies. These nerve blocks have been an effective addition to clinical anesthesia practice. The use of peripheral nerve blocks has improved postoperative pain, lessened the use of opioids and their potential side effects, and decreased the incidence of sleep disturbance in patients. More research should be done to further delineate the potential benefits of these blocks.

A randomized clinical trial on the effect of a lidocaine patch on shoulder pain relief in laparoscopic cholecystectomy

The incidence of laparoscopy-related shoulder pain reaches 90% in women. We evaluated the effect of lidocaine patch 5% on the shoulder pain after laparoscopic cholecystectomy (LC) in female patients. Total 63 female patients were randomly allocated to patch group (n = 31) and control group (n = 32). Patch group received lidocaine patch 5% and dressing retention tape on both shoulder, and control group received only dressing retention tape. Abdominal and shoulder pains were evaluated with rating on numeric rating scale (0 = no pain and 10 = the worst pain) at baseline and at 30 min, 6 h, 24 h, and 48 h after surgery. There were no significant differences in patient characteristics and operation details. The overall incidence of shoulder pain was significantly lower in patch group than in control group (42% vs. 78%, P = 0.005). The severity of shoulder pain also was significantly reduced in patch group compared to control group at 24 h and 48 h after surgery (P = 0.01 and P = 0.015, respectively). Complications related to lidocaine patch were not found except nausea. Lidocaine patch 5% reduced the incidence and severity of postoperative shoulder pain in female patients undergoing LC without complications.

The Use of Massage Therapy as a Nonpharmacological Approach to Relieve Postlaparoscopic Shoulder Pain: a Pediatric Case Report

INTRODUCTION

Postlaparoscopic shoulder pain (PLSP) has been well documented to effect patients following an abdominal or thoracic laparoscopic surgery. PLSP is characterized by referred pain that can occur both unilaterally or bilaterally, and is typically caused by phrenic nerve irritation. Current literature has focused on pharmacological treatment; however, there is limited evidence for the use of nonpharmacological management of PLSP in the pediatric population.

CASE DESCRIPTION

This retrospective case report study explores the use of a single-session massage therapy treatment for a 17-year-old patient with PLSP following laparoscopic abdominal surgery.

INTERVENTION AND RESULTS

Therapy intervention included a 25 min Swedish massage involving the effected shoulder with an emphasis on passive touch to the shoulder and at the level of the diaphragm. Pain was assessed using the Visual Analog Scale (VAS) pre- and postintervention. Following therapy the patient reported 0/10 pain.

CONCLUSION

This case report provides evidence for the use of massage therapy treatment as a noninvasive, nonpharmacological approach to reducing or eliminating PLSP in a pediatric patient.
