The role of pectoral nerve blocks in a day-case mastectomy service: A prospective cohort study.

ABSTRACT: Background:It is now recognised that the majority of breast surgery can be safely undertaken as day case procedures. We aimed to evaluate the effect of pectoral nerve (Pecs2) blocks on recovery parameters and day case rates in patients undergoing mastectomy for breast cancer. Methods:A prospective cohort study was performed in a single NHS Foundation trust between 1st April 2014 and 31st December 2016. Visual analogue scale (VAS) pain scores (0-10) at 4 and 8?h, episodes of post-operative nausea?±?vomiting (PONV), opioid use and day case outcome were compared between Pecs2 and no Pecs2 groups. Results:22 patients underwent general anaesthesia (GA) + Pecs2 block and 30 GA ± local anaesthetic infiltration.Mean pain scores were significantly lower in the Pecs2 (2.5) vs no Pecs2 (4.6) group at 4?h (p?=?0.0132) and 8?h, Pecs2 (1.9) vs no Pecs2 (3.6) (p?=?0.0038).Episodes of PONV requiring additional anti-emetic were lower and statistically significant in the Pecs2 group (2/22, 9%) than the no Pecs2 group (14/30, 46%), (p?=?0.005).Additional opioid use was significantly lower in the Pecs2 group (4/22, 18%) than in the no Pecs2 group (14/30, 46%) (p?=?0.0423).18 patients in the Pecs2 group were discharged the same day in contrast to just 3 patients in the no Pecs2 group. This was highly statistically significant (p?=?0.0001). Conclusions:Pecs2 blocks can significantly reduce post-operative pain, nausea and vomiting in patients undergoing mastectomy. Their use can enable units to achieve high day-case mastectomy rates.

Project description:BackgroundMany types of regional nerve blocks have been used during anesthesia for modified radical mastectomy. In recent years, the use of pectoral nerve (PECS) block has gained importance in postoperative analgesia, but there are still controversies regarding its efficacy. There is especially no consensus on the optimal type of PECS block to be used. Herein, we attempt to evaluate the analgesic efficacy of the PECS block after radical mastectomy.MethodsWe searched PubMed, EMBASE, and the Cochrane library for randomized controlled trials (RCTs) for studies regarding PECS versus general anesthesia (GA) that were published prior to May 31, 2018. Outcome measures such as intra- and postoperative consumption of opioids, postoperative nausea and vomiting (PONV), need for postoperative rescue analgesia, and pain scores were analyzed. After quality evaluation and data extraction, a meta-analysis was performed using Review Manager 5.3 software, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used for rating the quality of evidence.ResultsA total of 8 RCTs and 2 cohort studies involving 993 patients were eligible. Compared with the GA group, the PECS block group effectively reduced the intraoperative and postoperative use of opioid drugs, incidence of PONV, need for postoperative rescue analgesia, and pain scores within 0 to 6 hours after surgery. However, subgroup analysis showed that PECS I block did not have a significant advantage in reducing the intra- and postoperative consumption of opioids. Results for each outcome indicator were confirmed as having a high or moderate level of evidence.ConclusionsEven considering the limitations (evaluations of efficacy in different age groups and for chronic pain were not carried out) of this meta-analysis, it can be concluded that the PECS II block is an effective anesthetic regimen in modified radical mastectomy that can effectively reduce the intra- and postoperative consumption of opioids, postoperative PONV, and the need for postoperative rescue analgesia and can alleviate early pain (0-6 hours) after surgery.

Project description:Regional anesthesia between the pectoralis major and minor was first described in 2011 as an alternative method to paravertebral blocks or epidurals for post-operative mastectomies. Since then, the use of pectoral nerve (PECS) blocks for post-operative pain management following thoracotomy, sternotomy, and other procedures in the anterior thorax has increased. While experience with this block is growing, the current understanding of its use in pediatric patients is limited. We reviewed pediatric cases at a single institution and provide a descriptive account of our use of PECS I and II blocks for post-operative pain management following operations involving sternotomy in pediatric patients. We performed a retrospective database analysis of the use of PECS I and II blocks following procedures requiring sternotomy from 2018 to 2021 at St. Louis Children's Hospital. Patients 21 years old and younger who received either a PECS I or II block following a sternotomy for a cardiac procedure were included in the analysis. Patient's demographics, pre-, intra-, and post-operative medications, operative time, extubation status, pain evaluations, and hospital course were assessed from the electronic medical record. From 2018 to 2021, 73 ultrasound-guided PECS blocks were performed for pain relief for pediatric sternotomy. The most commonly performed operations were atrial septal defect closure (n = 12), mitral valve repair (n = 8), and ventricle septal defect closure (n = 8). Out of the 73 patients, 47 received a PECS I block and 26 received a PECS II Block. 70 of the blocks were administered after closure of the sternum while 3 were done before incision. The time to perform blocks took on average of 6 (±4) min. Mean operating room time was 7.5 h. Local anesthetics used for the blocks were as follows: Ropivacaine 0.2% (n = 54), Ropivacaine 0.5% (n = 18), and Bupivacaine 0.25% (n = 1). Twenty-five out of 73 patients did not experience severe pain, defined as ≥7/10 on a numeric pain scale, at any point in the first 24 h following surgery. We describe the of use PECS I and II nerve block following pediatric sternotomy. Blocks were straight forward to perform, and typically took a short amount of time to administer (6 min), when compared to the total operating room time (7.5 h). While this study did not include a comparative group that did not receive a block, 34 percent of patients did not suffer from severe pain in the first 24 h following surgery. Further prospective studies are needed to assess the effectiveness of PECS blocks for pain relief following sternotomy in pediatric patients when compared to current standard of care. PECS blocks may be beneficial for a range of cardiac surgeries that typically result in severe postoperative pain.
