The Effect of a Combined Modified Pectoral and Stellate Ganglion Block on Stress and Inflammatory Response in Patients Undergoing Modified Radical Mastectomy.

ABSTRACT:

Background and aims

Regional anaesthesia reports to attenuate stress and inflammatory responses associated with surgical resection; however, the effectiveness of combined nerve blocks is less often investigated. We evaluated whether a combination of a pectoral nerve block (PNB) and stellate ganglion block (SGB) is more effective than a PNB alone in reducing these responses in women undergoing modified radical mastectomy (MRM).

Methods

This is a prospective randomized controlled trial. Fifty patients with breast cancer were randomly allocated to receive an ultrasound-guided PNB (n = 25, PNB only group) or ultrasound-guided PNB combined with SGB (n = 25, combined blockade group). The primary outcome was perioperative plasma level of interleukin- (IL-) 6. Secondary outcomes included perioperative plasma levels of cortisol, glucose, IL-8, and tumour necrosis factor- (TNF-) α, pain scores, haemodynamic variables, sleep quality, and complications postsurgery.

Results

The combined blockade group exhibited significantly lower IL-6 and TNF-α levels 24 h postsurgery. Cortisol levels were significantly lower in the combined blockade group at the end of the surgery. Glucose levels at the time of incision were lower in the combined blockade group. Pain scores up to 12 h postsurgery were significantly lower in the combined blockade group, which also exhibited better perioperative haemodynamic stability. Patients in the combined blockade group reported better sleep quality on the night of surgery.

Conclusion

In patients undergoing MRM, PNB combined with SGB block effectively blunted perioperative inflammatory response than PNB alone. A combined block approach can also alleviate stress response and postoperative acute pain with stable perioperative haemodynamics and better postoperative sleep quality.

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:Background and objectivesParavertebral block placement was the main anesthetic technique for modified radical mastectomy in our hospital until February 2014, when its combination with blocks targeting the pectoral musculature was initiated. We compared the analgesic effects of paravertebral blocks with or without blocks targeting the pectoral musculature for modified radical mastectomy.MethodsWe retrospectively collected data from a single surgeon and anesthesiologist from June 1, 2012, to May 31, 2015. Intraoperative sedatives and analgesic requirements, time to the first analgesic request, postoperative analgesic doses, patient satisfaction, and complications were compared.ResultsFifty-four patients received a paravertebral block alone (PECS 0), and 46 received a paravertebral block combined with blocks targeting the pectoral musculature (PECS 1). The highest intraoperative effect-site concentration of propofol was significantly lower in the PECS 1 group than in the PECS 0 group [2.3 (1.5, 2.8) vs 2.5 (1.5, 4) μg/mL, p = 0.0014]. The intraoperative rescue analgesic dose was significantly lower in the PECS 1 group [0 (0, 25) vs 0 (0, 75) mg of ketamine, p = 0.0384]. Furthermore, the PECS 1 group had a significantly longer time to the first analgesic request [636.5 (15, 720) vs 182.5 (14, 720) min, p = 0.0001]. After further adjustment for age, body mass index, American Society of Anesthesiologists Physical Status classification, chronic pain history, incidence of a superficial cervical plexus block placement, and operation duration, blocks targeting the pectoral musculature were determined to be the only significant factor (hazard ratio, 0.36; 95% confidence interval, 0.23-0.58; p < 0.0001). Very few patients used potent analgesics including morphine and ketorolac; the cumulative use of morphine or ketorolac was similar in the study groups. However, the incidence of all analgesic use, namely morphine, ketorolac, acetaminophen, and celecoxib, was significantly lower in the PECS 1 group [3.5 (0, 6) vs 5 (0, 12), p < 0.0001].ConclusionsCompared with the placement of a paravertebral block alone, combining blocks targeting the pectoral musculature with a paravertebral block for modified radical mastectomy reduced the sedative and analgesic requirements during operation and provided more effective postoperative analgesia.

Project description:BackgroundBreast cancer has overtaken lung cancer as the most commonly diagnosed malignancy and is the leading cause of cancer-related death in women. Surgery is the only possible cure for breast cancer, and the incidence of acute postoperative pain (APP) is high in breast surgery. Previous reports suggested that ultrasound-guided deep serratus anterior plane block (dSAPB) provided effective blockade to relieve pain after modified radical mastectomy for breast cancer. In fact, despite the long-acting local anesthetic agents used, the patient's pain cannot completely be eliminated due to the short duration of anesthesia. Dexmedetomidine as an adjunct to local anesthetics can prolong peripheral nerve block duration. However, no study has investigated the role of dSAPB with dexmedetomidine in the quality of recovery scores undergoing modified radical mastectomy. Thus, this study was conducted aiming at this aspect.Material and methodsThis single-center, double-blind, randomized clinical trial was conducted at Bethune International Peace Hospital. A total of 88 participants of elective modified radical mastectomy were enrolled from May and November 2021. Ultrasound-guided dSAPB combined with 30 ml of 0.375% ropivacaine or 30 ml of 0.375% ropivacaine with dexmedetomidine (1 μg/kg) was administrated before anesthesia at the fourth to fifth ribs of the axillary midline. The primary outcome was quality of recovery, measured 24 h postoperatively using the QoR-15. Secondary outcomes were the Visual Analogue Scale (VAS) scores at rest and movement at 1, 6, 12, 24, and 48 h after surgery, 48 h sufentanil consumption postoperatively, the incidence of postoperative nausea and vomiting (PONV), length of post-anesthesia care unit (PACU) stay, dizziness, delirium, SAPB-related adverse events, and patient's satisfaction with pain management.ResultsAmong the 88 participants, 8 did not meet the inclusion criteria; the other 80 were randomized to receive dSAPB combined with ropivacaine (Group R, N=40) and dSAPB combined with ropivacaine plus DEX (Group RD, N=40), of which a total of 7 (4 in Group R and 3 in Group RD) were excluded due to protocol deviation. Eventually,73 participants (36 in Group R and 37 in Group RD) were included for final analysis, with age (SD, years, 54.08[6.28] vs. 54.62[7.44], p=0.740), body mass index (BMI) (SD, 27.96[1.67] vs. 27.57[2.38], p=0.428), and median preoperative global QoR-15 score (interquartile range (IQR), 127[123.25-131] vs. 126[121-130], p=0.662). The median postoperative global QoR-15 score (IQR, 107[103-112] vs. 109.5[107-114], p=0.016), VAS score at rest at 12th hour (IQR, 1[1-2] vs. 1[1-2], p=0.033), VAS score in movement at 12th hour (IQR, 2[1-3] vs. 2[1-3], p=0.014) and at 24th hour (IQR, 3[2-3] vs. 3[2-3], p=0.040), and median sufentanil rescues consumption (IQR, 14[12-17 vs. 14[12-15], p=0.022] of Group RD were significantly lower than those of the Group R. Patient satisfaction score (SD, 8.28[0.70] vs. 8.62[0.59], p=0.024) of Group RD were significantly higher than those of the Group R.ConclusionThe ultrasound-guided dSAPB combined with dexmedetomidine plus ropivacaine may improve the QoR-15 in patients undergoing modified radical mastectomy and indicates that it may be a useful intervention to aid recovery following breast cancer surgery. Furthermore, participants in the ropivacaine with DEX group met the superior pain relief in the early postoperative period, reduced postoperative cumulative opioid consumption, increased patient satisfaction, and no increase in the incidence of complications.

Project description:IntroductionPotent analgesics such as sufentanil and remifentanil play a pivotal role in general anesthesia, but these medications have disadvantages, including respiratory depression, nausea, vomiting, immune system suppression, and gastrointestinal function inhibition. This study aimed to evaluate the effects of the transversus thoracic muscle plane-pectoral nerves (TTP-PECS) block on postoperative analgesia, immune function and early postoperative recovery quality in patients undergoing modified radical mastectomy under opioid-sparing general anesthesia.MethodsA total of 100 patients scheduled for modified radical mastectomy under general anesthesia were randomly divided into the TTP-PECS block combined with opioid-sparing general anesthesia group (TO group, n = 50) or the conventional general anesthesia group (GA group, n = 50). The TO group underwent TTP-PECS block prior to induction, using oxycodone as the analgesic during induction instead of sufentanil, no additional continuous infusion of analgesic was performed intra-operatively. Visual analogue scale (VAS) scores at rest and during movement at different time points were recorded in both groups, and the levels of T cell subsets, natural killer (NK) cells were measured before the surgery and at 24 h and 48 h after the surgery. Quality of Recovery-40 (QoR-40) scores were assessed at 24 h postoperatively, and the incidence of peri-operative adverse reactions was also observed in both groups.ResultsExcept for 48 h postoperatively, patients in the TO group had significantly lower VAS scores than those in the GA group at 2 h, 6 h, 12 h, and 24 h postoperatively at rest and during movement (P < 0.05). At 24 h and 48 h postoperatively, the expression of CD4+ T cells and the CD4+/CD8+ ratio were significantly higher in the TO group than in the GA group (P < 0.05). The QoR-40 scale, assessed at 24 h postoperatively, showed that the TO group significantly outperformed the GA group in total scores as well as in sub-scores for emotional state, physical comfort, physical independence, psychological support, and pain (P < 0.05). In addition, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were lower at time points T1-T4 than at T0 in both groups (P < 0.05), but the differences between the two groups were not statistically significant(P > 0.05). The incidence of cough reflex during induction and postoperative nausea and vomiting were significantly lower in the TO group than in the GA group (P < 0.05). There was no statistically significant difference between the two groups in the incidence of other adverse reactions (P > 0.05).ConclusionsThe combination of TTP-PECS block and oxycodone-propofol opioid-sparing general anesthesia can provide superior postoperative analgesia and reduce the incidence of postoperative nausea and vomiting. It also alleviated the suppression of cellular immune function and improves the quality of early recovery in breast cancer patients. At the same time, opioid-sparing general anesthesia is a safe strategy for modified radical mastectomy.Trial registrationChinese Clinical Trial Registry; ChiCTR2200066753.

Project description:BackgroundInadequate acute postoperative pain management is linked to the effect on the stress response and development of chronic pain. A unique regional anaesthetic method that is becoming more important for postoperative pain management is erector spinea plane block (ESP). Since its initial description, physicians have questioned weather this novel easy method can take the place of paravertebral block (PVB). Our goal was to evaluate, in contrast to control group, the effects of ESP & PVB on acute and chronic post-mastectomy pain.MethodsOne hundred and five female patients undergoing modified radical mastectomy participated in this study, randomly allocated into three equal groups: erector spinae plane block (ESP), thoracic paravertebral (TPV), and control groups. Both blocks were ultrasound-guided with 20 ml 0.25% bupivacaine according to patients' group, control group was administered standard general anaesthesia without intervention. Total morphine consumption in the first 24 h postoperative was the primary outcome. The secondary outcomes were time to the first analgesia, (Visual Analogue Scale)VAS score, serum level of cortisol and prolactin, sedation score, side effects, and LANSS scores in the first, third, and sixth postoperative months were among the variables compared between groups.ResultsTotal morphine consumption in the first 24 h was significantly higher in control than ESP and TPV groups (10.74 ± 1.37, 8.17 ± 1.69, 5.70 ± 1.95 respectively p < 0.001). Time to first analgesic request was the shortest in control versus ESP and TPV groups as (4.37 ± 3.06, 8.13 ± 1.75, 10.64 ± 1.83 h respectively p ˂0.001). ESP and TPV had significantly lower cortisol and prolactin levels compared to control (p < 0.001). The highest LANSS scores were in the control group in the first, third, and sixth months compared with ESP and TPV, with no significant difference between ESP and TPV.ConclusionESP and TPV blocks provided superior early postoperative analgesia and reduced stress response compared to the control group in female patients undergoing modified radical mastectomy. PVB is better than ESB in acute postoperative pain management (the total morphine consumption VAS score and time of first analgesic request). Both techniques showed better long-term outcomes compared to the control group regarding LANSS score in the 6-month follow-up.Trial registrationhttps://www.Clinicaltrialsgov trial registry (identifier NCT04498234 on 04/08/2020).
