The Role of Ultrasound-Guided Multipoint Fascial Plane Block in ElderlyPatients Undergoing Combined Thoracoscopic-Laparoscopic Esophagectomy: A Prospective Randomized Study

INTRODUCTION

We estimated the safety and efficacy of ultrasound-guided multipoint fascial plane block, including serratus anterior plane block (SAPB) and bilateral transversus abdominis plane block (TAPB) in elderly patients who underwent combined thoracoscopic-laparoscopic esophagectomy (TLE).

METHODS

The authors enrolled 80 patients in this prospective study after patient selection using the inclusion and exclusion criteria who were scheduled for elective TLE from May 2020 to May 2021. Patients were randomly assigned to the treated group (group N) or the control group (group C) (n = 40 per group) using the sealed-envelope method. Multipoint fascial plane blocks, including serratus anterior plane block (SAPB) and bilateral TAPB, were performed on patients undergoing TLE using a solution of 60 mL 0.375% ropivacaine plus 2.5 mg dexamethasone by 3 injections of 20 mL each (group N) or no interventions (group C).

RESULTS

Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) at T incision and 30 min after T incision were significantly higher in group C than in group N, and also significantly higher than at baseline (P < 0.01). Blood glucose at 60 min, 2 h after T incision, was significantly higher in group C than in group N and significantly higher than at baseline (P < 0.01). Compared to group N, the dosages of propofol and remifentanil used during surgery in group C were more than those in group N (P < 0.01). The time to first rescue analgesic in group C was earlier than in group N. The total postoperative use of sufentanil, and the number of patients requiring rescue analgesics in group C, were more than in group N (P < 0.01).

CONCLUSIONS

This study showed that applying the multipoint fascia pane block technique in TLE for elderly patients could significantly reduce postoperative pain, decrease the dosages of drugs used in general anesthesia, improve the quality of the awakening, and have no obvious adverse reactions.

Postoperative pain: a review of emerging therapeutic options

INTRODUCTION

Postoperative pain is often managed by opioid medications, even though they carry a risk of adverse effects such as vomiting, constipation, sedation, respiratory depression and physical dependence. Furthermore, opioid use in the healthcare setting has likely contributed to the epidemic. However, the mismanagement of postoperative pain can result in delayed recovery time, impaired physical function, increased risk of morbidity and mortality, chronic pain, and higher healthcare costs.

AREAS COVERED

This review explores emerging therapeutic options and strategies in the management of acute postoperative pain and focuses on opioid-sparing, multimodal analgesia. This includes regional anesthetic techniques, non opioid pharmacotherapy, novel opioids and non-pharmacologic therapy. We have also discussed examples of novel analgesics and formulations which have potential benefits in reducing postoperative pain and opioid use after surgery.

EXPERT OPINION

The development of novel regional anesthesia techniques allows for opioid minimization in increasing number of surgical procedures. This synergizes with the availability of novel non-opioid analgesic adjucts. In addition, several novel opioid drugs have been developed which may be pathway selective and associated with less adverse effect than conventional opioids.

A case report of arthroscopic surgery under extended spinal anesthesia for 402 minutes, assisted by monitored anesthesia care

Introduction

Surgical spinal anesthesia is usually maintained for approximately 3 h with bupivacaine, but it is difficult to accurately predict the duration of surgery for each case. When an operation continues for an extended duration, regression of spinal anesthesia often leads to general anesthesia. Here we present a case of extended spinal anesthesia assisted by monitored anesthesia care.

Case presentation

A 32-year-old male who suffered from persistent pain of the right knee was diagnosed with rupture of the right anterior cruciate ligament. Arthroscopic surgery of the right knee was conducted with spinal anesthesia. A local anesthetic mixture of 0.5% hyperbaric bupivacaine 12 mg with 50 μg of epinephrine was used. The surgery took longer than expected with a total anesthesia time of 402 minutes. In the final 30 minutes of surgery, spinal anesthesia regressed and the procedure was completed under monitored anesthesia care (MAC).

Clinical discussion

When spinal anesthesia is on regression during the final stage of surgery, the application of MAC safely secures additional operation time. By adopting MAC, the patient avoided general anesthesia and had minimal physiological distress and a rapid recovery. Another benefit of MAC is the reduced consumption of resources. Further, by avoiding endotracheal intubation and mechanical ventilation, the risk of transmission of infectious agents is minimized.

Conclusion

In situations where spinal anesthesia is regressing close to the end of a surgical procedure, the application of MAC has potential benefits over general anesthesia. These benefits are particularly relevant during the current COVID-19 pandemic.

•

The duration of spinal anesthesia is difficult to predict in each surgical patient.

•

In this case, spinal anesthesia had lasted for 402 minutes, eventually on regression.

•

Instead of conversion into general anesthesia, monitored anesthesia care is adopted.

•

The patient had rapid recovery and there was a minimal physiologic disturbance.

•

There are additional benefits of monitored anesthesia care for the COVID-19 pandemic.

Evaluation of postoperative pain in patients undergoing modified radical mastectomy with pectoralis or serratus-intercostal fascial plane blocks

Background

Regional nerve blocks are an integral part of multimodal analgesia and should be chosen based on their efficacy, convenience, and minimal side effects. Here, we compare the use of pectoral (PEC II) and serratus-intercostal fascial plane (SIFP) blocks in breast carcinoma cases undergoing modified radical mastectomy in terms of the postoperative analgesic efficacy and shoulder mobility.

Methods

The primary outcome of this prospective controlled study was to compare the postoperative static and dynamic pain scores, and the secondary outcome was to assess the shoulder pain, range of shoulder joint motion, and hemodynamic parameters. Sixty patients were randomly allocated to three groups and given general anesthesia. All patients received paracetamol, diclofenac, and rescue doses of tramadol based on the institute's acute pain service policy. No block was performed in group C (control), whereas groups P and S received PEC II and SIFP blocks, respectively, before surgical incision.

Results

The groups were comparable in terms of age, weight, height, and body mass index distribution. Dynamic pain relief was significantly better 12 and 24 h postoperatively in groups P (P = 0.034, P = 0.040 respectively) and S (P = 0.012 and P = 0.017, respectively) compared to group C. Shoulder pain relief and shoulder mobility were better in group S, while the hemodynamic parameters were more stable in group P.

Conclusions

Both SIFP and PEC blocks have comparable dynamic and static pain relief with better shoulder pain scores in patients receiving SIFP.
