Feasibility and effectiveness of multi-injection thoracic paravertebral block via the intrathoracic approach for analgesia after thoracoscopic-laparoscopic esophagectomy.

ABSTRACT:

Background

We observed the feasibility and effectiveness of multi-injection thoracic paravertebral block (TPB) via the intrathoracic approach under thoracoscopic direct vision for analgesia after thoracoscopic-laparoscopic esophagectomy (TLE).

Methods

Sixty patients undergoing TLE were randomly divided into a control group and an observation group. All patients underwent TPB via the intrathoracic approach at the three levels of T2, 5, and 8 with a scalp needle before closing the chest. The patients in the observation group received 10 ml 0.375% ropivacaine at each level, and the patients in the control group received 10 ml of 0.9% saline at each level. A patient-controlled intravenous analgesic (PCIA) pump with sufentanil was attached to all patients after surgery. The sufentanil consumption, number of PCIA presses and use of rescue analgesia in the first 24 h after surgery were recorded. The visual analogue scale (VAS) scores (rest and coughing) were recorded at 2 h, 6 h, 12 h, 24 h, and 48 h after surgery. The duration of postoperative hospital stay, active cough rate, first ambulation, and the incidence of adverse reactions after surgery was recorded.

Results

The sufentanil consumption in the observation group was significantly lower than that in the control group (34.7 ± 1.9 µg vs. 52.1 ± 2.1 µg; P < 0.001). The VAS score at each postoperative time point, number of PCIA presses, use of rescue analgesia, and the incidence of adverse reactions in the observation group were significantly lower than those in the control group. The postoperative active cough rate of patients in the observation group was significantly higher than those in the control group, and the times of the first ambulation after surgery and postoperative hospital stay in the observation group were significantly shorter than those in the control group (all P < 0.05).

Conclusions

Multi-injection TPB via the intrathoracic approach under thoracoscopic direct vision is easy to perform and can effectively alleviate postoperative pain after TLE with fewer adverse reactions and contributing to improved postoperative recovery.

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:BackgroundTo investigate the effects of body mass index (BMI) on intensity postoperative pain in patients who underwent thoracic paravertebral block (TPVB) for postoperative analgesia after video-assissted thoracoscopic surgery (VATS).MethodsPatients aged 18-80 years, ASA I-III, and BMI 18-40 kg/m2 who underwent elective VATS were included in the study. The patients were divided into 3 groups according to their BMI levels. TPVB was performed under ultrasound-guidance at the fifth thoracic vertebrae, and 30 ml of 0.25% bupivacaine was injected. The patient-controlled analgesia (PCA) was performed by using morphine and multimodal analgesia was performed. As a rescue analgesic agent, 0.5 mg/kg tramadol was given to patients intravenously when a score of visual analog scale (VAS) at rest was ≥ 4. The primary outcome was determined as VAS scores at rest and cough. Secondary outcomes were determined as postoperative morphine consumption, additional analgesic requirement, and side effects.ResultsThe post-hoc test revealed that the VAS resting scores at the 4th hour (p: 0.007), 12th hour (p: 0.014), and 48th hour (p: 0.002) were statistically significantly lower in Group I compared to Group II. Additionally, VAS resting scores were also statistically significantly lower in Group I compared to Group III at all time points (p < 0.05). Similarly, the post-hoc test indicated that the VAS coughing scores at the 4th hour (p: 0.023), 12th hour (p: 0.011), and 48th hour (p: 0.019) were statistically significantly lower in Group I compared to Group II. Moreover, VAS coughing scores were statistically significantly lower in Group I compared to Group III at all time points (p < 0.001). Furthermore, there were statistically significant differences in terms of additional analgesic use between the groups (p: 0.001). Additionally, there was a statistically significant difference in terms of morphine consumption via PCA and morphine milligram equivalent consumption between the groups (p < 0.001).ConclusionsHigher postoperative VAS scores with TPVB applied in obese patients and the consequent increase in additional analgesics and complications require more specific postoperative management in this patient group.

Project description:IntroductionErector spinae plane block (ESPB) is a novel inter-fascial plane block, which is applied more and more in postoperative pain control, especially in chest surgery. Regional block is advocated in order to decrease opioid consumption and improve analgesia in urological surgery. Therefore, we aimed to explore whether ESPB would have similar analgesia compared with thoracic paravertebral block (TPVB) in laparoscopic nephroureterectomy.Methods and analysisThis prospective, randomized, double-blinded, non-inferiority trial will enroll 166 patients undergoing laparoscopic nephroureterectomy. Participants will be randomly assigned 1:1 into receiving ESPB or TPVB before surgery. Both ultrasound-guided ESPB and TPVB will be performed with an injection of 0.375% ropivacaine 0.4 ml/kg before anesthesia induction. Standardized patients controlled intravenous analgesia (PCIA) will be applied for each patient. The primary endpoint is the joint of cumulative 24 h opioid (sufentanil) consumption and average pain score via numeric rating scale (NRS) at 24 h after surgery. Secondary endpoints include rescued analgesic demand, cumulative opioid consumption, and pain NRS scores at different preset timepoints within 48 h after surgery. Other predefined outcomes include clinical features of blockage, quality of recovery, subjective sleep quality, time to ambulation and diet, and adverse events, as well as length of stay in hospital and anesthesia cost.DiscussionPrevious studies investigating the analgesic efficacy of ESPB only concentrated on a single endpoint for postoperative pain evaluation, while studies focusing on the direct comparison between ESPB and TPVB in urological surgery are still lacking. Our study is the first trial in non-inferiority design of comparing ESPB and TPVB in patient undergoing laparoscopic nephroureterectomy, and the primary outcome is the joint endpoint of opioid consumption and pain NRS score.Trial registrationChinese Clinical Trial Registry ChiCTR 2000031916 .

Project description:ObjectivesTo assess the effects of thoracic paravertebral block and s-ketamine on postoperative pain and perioperative neurocognitive disorder (PND) in video-assisted thoracoscopic surgery.MethodsPatients (n = 120) aged 45-65 undergoing video-assisted thoracoscopic surgery were allocated randomly into the following three groups: patients in the C group received general anaesthesia; patients in the thoracic paravertebral block group, i.e. the TP group, received general anaesthesia and ultrasound-guided paravertebral block; and patients in the s-ketamine combined with ultrasound-guided thoracic paravertebral nerve block group, i.e. the TS group, received combined anaesthesia, which was administered as follows: general anaesthesia + ultrasound-guided paravertebral block + perioperative s-ketamine (a bolus of 0.3 mg/kg, followed by an infusion of 0.2 mg/kg/h until 30 min before the end of the surgical procedure).ResultsCognitive function was measured using the Mini-Mental State Examination 1 day preoperatively, 1 day postoperatively, and 3 months postoperatively. Z-score was used to determine the incidence of PND. Postoperative pain was assessed using the visual analogue scale at 0.5 and 24 h postoperatively. The use of opioid drugs, intraoperative vital signs, and other secondary outcomes were also recorded. The final analysis included a total of 110 patients. The intraoperative heart rate and mean arterial pressure in the TS and TP groups were lower than that for group C (P＜0.05). After surgery, patients in the TS group exhibited significantly lower pain scores at 0.5 h and 24 h (P＜0.001 and P = 0.004,respectively) as well as significantly lower rates of postoperative nausea, vomiting, and pulmonary complications (P＜0.05). The incidence of PND in the TP and TS groups was lower than those who received general anaesthesia. However, there was no significant difference in the incidence of PND between the TP and TS groups (P＞0.05).ConclusionsUltrasound-guided paravertebral nerve block combined with s-ketamine decreased acute postoperative pain and improved the quality of recovery. However, perioperative s-ketamine did not improve cognitive function in patients under general anaesthesia with thoracic paravertebral block.

Project description:IntroductionPostoperative pain is a main component influencing the recovery of patients with lung cancer. The combination of patient-controlled intravenous analgesia (PCIA) and paravertebral nerve block for postoperative analgesia in patients undergoing thoracoscopic lobectomy for lung cancer can achieve a satisfactory analgesic effect and promote early rehabilitation of patients. The objective is to investigate the optimal dose of oxycodone for PCIA combined with paravertebral nerve block, to achieve effective multimodal analgesia management in patients undergoing thoracoscopic lung cancer lobectomy.Methods and analysisThis prospective, double-blind, single-centre, parallel-group, superiority study from 7 April 2023 to 31 December 2024 will include 160 participants scheduled for thoracoscopic lobectomy for lung cancer. Participants will be randomly assigned to four groups in a 1:1:1:1 ratio: OCA group (oxycodone: 0.5 mg/kg), OCB group (oxycodone: 1.0 mg/kg), OCC group (oxycodone: 1.5 mg/kg) and one sufentanil group (sufentanil: 2 µg/kg). Flurbiprofen 50 mg and ondansetron 16 mg are added to each group. All the drugs are diluted with 0.9% saline in a 100 mL volume, with a background infusion rate of 2 mL/hour, a bolus dose of 0.5 mL and a lockout interval of 15 min. The primary outcome is pain scores at rest and dynamic at 24 hours after surgery using a Numeric Rating Scale (NRS). Dynamic NRS scores are defined as NRS when coughing. NRS scores will be assessed at 2, 4, 12, 24 and 48 hours postoperatively. The secondary outcomes include the following variables: (1) NRS score at rest and dynamic at 2, 4, 12 and 48 hours postoperatively; (2) total dose of sufentanil or oxycodone consumption in PCIA; (3) the times of patient-controlled analgesia; (4) Ramsay Sedation Score (RSS) at 2, 4, 12, 24 and 48 hours after the surgery; (5) extubation time; (6) serum C-reactive protein and interleukin six levels; (7) incidence of postoperative nausea and vomiting; (8) incidence of itching; (9) incidence of respiratory depression and (10) gastrointestinal recovery (exhaust time).Ethics and disseminationThe First Affiliated Hospital of Shandong First Medical University's Ethics Committee granted consent for this study (approval number: YXLL-KY-2022(116)).
