Abstract
Purpose To explore the benefits of ultrasound-guided intermittent thoracic paravertebral block (TPVB) combined with intravenous analgesia (PCIA) in alleviating postoperative nausea and vomiting (PONV) during video-assisted thoracic surgery (VATS). Patients and Methods 120 patients with lung carcinoma undergoing VATS were included and divided into three groups: group S (single TPVB+PCIA), group I (intermittent TPVB+PCIA), and group P (PCIA). The patients' NRS scores, postoperative hydromorphone hydrochloride consumption, and intramuscular injection of bucinnazine hydrochloride were recorded. The incidence of PONV and complications were documented. Results Compared with the group P, both group I and group S had significantly lower static NRS scores from 1-48 hours after the operation (P <0.05), and the dynamic NRS score of group I at the 1-48 hours after the operation were significantly decreased (P <0.05). Compared with the group P, the proportion of patients with PONV in group I was significantly lower (P <0.05), while there was no significant difference in group S. Moreover, the hospitalization period of patients in group I was significantly reduced compared with the other two groups (P <0.01), and the patient satisfaction was significantly increased compared with the group P (P <0.05). Conclusion Intermittent TPVB combined with PCIA can reduce the postoperative pain and the occurrence of PONV.

Comparative evaluation of continuous infusion versus programmed intermittent bolus techniques in erector spinae plane block in modified radical mastectomy - A preliminary randomised controlled trial. Indian J Anaesth 2024; 68:273-279. [PMID: 38476552 PMCID: PMC10926334 DOI: 10.4103/ija.ija_922_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 12/13/2023] [Accepted: 12/20/2023] [Indexed: 03/14/2024] Open
Abstract
Background and Aims Single-shot erector spinae plane block (ESPB) provides excellent analgesia in mastectomy in the immediate post-operative period but is not sufficient to maintain for prolonged duration. This study compares the efficacy of programmed intermittent bolus (PIB) versus continuous infusion (CI) techniques after ESPB by placing a catheter for mastectomy. Methods After ethical approval and patient consent, ESPB was performed at the T4 level in 50 patients with an initial bolus of 20 mL 0.375% ropivacaine and a catheter placed 30 min before surgery. In the postoperative period, they were randomised to Group I - intermittent bolus of 20 mL 0.2% ropivacaine every 4 h for 24 h and Group C - continuous infusion of 0.2% ropivacaine at 5 mL/h for 24 h. The primary outcome was the 24-h fentanyl consumption by patient-controlled analgesia device. Data was analysed using Stata 14.0. Results Group I patients had reduced post-operative fentanyl consumption {mean [standard deviation (SD)]: 166 (139.17) µg vs 332 (247.96) µg, P = 0.002} and lower median NRS scores (1 h: 3 vs 5), (2 h: 3 vs 5), (4 h: 3 vs 5), (6 h: 4 vs 5) with a higher mean (SD) Quality of Recovery-15 score {134.4 (8.53) vs 127 (12.89), P = 0.020} compared to Group C, respectively. The 24-h dermatomal sensory coverage was more comprehensive in Group I compared to Group C. Conclusion The PIB technique after ESPB provides decreased postoperative opioid consumption, better post-operative analgesia and quality of recovery compared to the CI technique in patients undergoing mastectomy.

Abstract
Objective The programmed intermittent bolus infusion (PIBI) of local anesthetic produces wider sensory blockade and better analgesia than continuous infusion (CI). We designed this trial to compare the effects of these two different infusion methods combined with Serratus Anterior Plane Blocks (cSAPBs) on postoperative pain relief in patients undergoing video-assisted thoracoscopic surgery. Methods We randomly allocated 66 patients under going elective video-assisted thoracoscopic unilateral lung resection surgery to two groups (PIBI group and CI group, n=33 per group). After the surgical operation, the patients received ultrasound-guided ipsilateral SAPB, we randomized them to receive either automated intermittent boluses or continuous infusion of 0.3% ropivacaine. Tramadol consumption during the 48 hours following surgery was the primary outcome. Secondary outcomes included cumulative tramadol consumption during the first 24-h and the second 24-h periods after surgery, pain scores, patient satisfaction, blocked dermatomes, and adverse events. Results During 48h, tramadol consumption in the PIBI group was significantly lower than in the CI group (190 mg [125, 305] vs 220 mg [170, 480], p= 0.034). As compared to the CI group, the PIBI group consumed less tramadol during the first 24 hours (145 mg [87.5, 210] vs 190 mg [140, 400], p=0.012). The dermatomes anesthetized to the pinprick and cold test were significantly more abundant in the PIBI group than in the CI group (3 [3,4] vs. 5 [4,5], p<0.001). Both groups had similar VAS scores at rest and when moving (p>0.05). Additionally, the PIBI group showed greater patient satisfaction. Both groups experienced similar adverse events (p>0.05). Conclusion Compared with CI, PIBI administration regimen (0.3% ropivacaine 5 mL/h) for cSAPBs resulted in lower tramadol consumption, superior analgesia during the initial 12 h after the operation, and higher patient satisfaction. PIBI combined with cSAPBs was a better choice for postoperative analgesia in patients undergoing video-assisted thoracoscopic surgery.

Abstract
BACKGROUND The analgesic characteristics of rhomboid intercostal block (RIB) remain unclear. Before it can be fully recommended, we compared the recovery quality and analgesic effects of RIB and thoracic paravertebral block (TPVB) for video-assisted thoracoscopic surgery (VATS). OBJECTIVE The current study aimed to investigate whether there is a difference in postoperative recovery quality between TPVB and RIB. DESIGN A prospective, non-inferiority, randomised controlled trial. SETTING Affiliated Hospital of Jiaxing University in China from March 2021 to August 2022. PATIENTS Eighty patients aged 18 to 80 years, with ASA physical status I to III, and scheduled for elective VATS were enrolled in the trial. INTERVENTION Ultrasound-guided TPVB or RIB was performed with 20 ml 0.375% ropivacaine. MAIN OUTCOME MEASURES The primary outcome of the study was the mean difference of quality of recovery-40 scores 24 h postoperatively. The non-inferiority margin was defined as 6.3. Numeric rating scores (NRS) for pain at 0.5, 1, 3, 6, 12, 24 and 48 h postoperatively in all patients were also recorded. RESULTS A total of 75 participants completed the study. The mean difference of quality of recovery-40 scores 24 h postoperatively was -1.6 (95% CI, -4.5 to 1.3), demonstrating the non-inferiority of RIB to TPVB. There was no significant difference between the two groups in the area under the curve for pain NRS over time, at rest and on movement, at 6, 12, 24 and 48 h postoperatively (all P > 0.05), except for the area under the curve pain NRS over time on movement at 48 h postoperatively ( P = 0.046). There were no statistical differences between the two groups in the postoperative sufentanil use at 0 to 24 h or 24 to 48 h (all P > 0.05). CONCLUSION Our study suggests that RIB was non-inferior to TPVB for the quality of recovery, with almost the same postoperative analgesic effect as TPVB after VATS.

Abstract
BACKGROUND We aimed to investigate the effects of intermittent bolus paravertebral block on analgesia and recovery in open hepatectomy. METHODS Eighty 18-70 years old, American Society of Anesthesiologists level I-III patients scheduled for hepatectomy with a J-shaped subcostal incision were enrolled and randomized to receive either intermittent bolus paravertebral ropivacaine (0.5% loading, 0.2% infusion) or 0.9% saline infusion at 1:1 ratio (25 ml loading before surgery, 0.125 ml/kg/h bolus for postoperative 48 h). The primary outcome was set as postoperative 48 h cumulative intravenous morphine consumption recorded by a patient-controlled analgesic pump. RESULTS Thirty-eight patients in each group completed the study. The cumulative morphine consumptions were lower in the paravertebral block than control group at postoperative 24 (difference -10.5 mg, 95%CI -16 mg to -6 mg, P < 0.001) and 48 (difference -12 mg, 95%CI -19.5 mg to -5 mg, P = 0.001) hours. The pain numerical rating scales at rest were lower in the paravertebral block than control group at postoperative 4 h (difference -2, 95%CI -3 to -1, P < 0.001). The active pain numerical rating scales were lower in the paravertebral block than control group at postoperative 12 h (difference -1, 95%CI -2 to 0, P = 0.005). Three months postoperatively, the paravertebral block group had lower rates of hypoesthesia (OR 0.28, 95%CI 0.11 to 0.75, P = 0.009) and numbness (OR 0.26, 95%CI 0.07 to 0.88, P = 0.024) than the control group. CONCLUSIONS Intermittent bolus paravertebral block provided an opioid-sparing effect and enhanced recovery both in hospital and after discharge in patients undergoing hepatectomy.

Abstract
During the past decade, numerous efforts were undertaken aiming at prolonging the analgesic effect of regional anesthesia. With the development of extended-release formulations and enhanced selectivity for nociceptive sensory neurons, a very promising contribution to the development of pain medications has been achieved. At present, liposomal bupivacaine is the most popular, non-opioid, controlled drug delivery system, but its duration of action, which is still controversially discussed, and its expensiveness have decreased initial enthusiasm. Continuous techniques can be seen as an elegant alternative for providing a prolonged duration of analgesia, but for logistic or anatomical reasons, they are not always the best choice. Therefore, focus has been directed towards the perineural and/or intravenous addition of old and established substances. As for perineural application, most of these so-called 'adjuvants' are used outside their indication, and their pharmacological efficacy is often not or only poorly understood. This review aims to summarize the recent developments for prolonging the duration of regional anesthesia. It will also discuss the potential harmful interactions and side effects of frequently used analgesic mixtures.

Abstract
BACKGROUND The optimal form of administration for erector spinae plane block has not been established. OBJECTIVE To compare the efficacy of programmed intermittent bolus infusion (PIB) and continuous infusion for erector spinae plane block. DESIGN A prospective, randomised, double-blind study. SETTING A single centre between June 2019 and March 2020. PATIENTS Included patients had an American Society of Anesthesiologists physical status 1 to 3 and were scheduled for video-assisted thoracic surgery. INTERVENTIONS Patients were randomised to receive continuous infusion (0.2% ropivacaine 8 ml h-1; Group C) or PIB (0.2% ropivacaine 8 ml every 2 h; Group P). MAIN OUTCOME MEASURES The primary outcome was the number of desensitised dermatomes in the midclavicular line, measured 21 h after first bolus injection. RESULTS Fifty patients were randomly assigned to each group; finally, the data of 24 and 25 patients in Group C and P, respectively, were analysed. The mean difference in the number of desensitised dermatomes in the midclavicular line at 5 and 21 h after the initial bolus administration was 1.0 [95% confidence interval (CI) 0.5 to 1.5] and 1.6 (95% CI 1.1 to 2.0), respectively, which was significantly higher in Group P than in Group C (P < 0.001). The median difference in rescue morphine consumption in the early postoperative period (0 to 24 h) was 4 (95% CI 1 to 8) mg, which was significantly lower in Group P (P = 0.035). No significant difference in the postoperative numerical rating scale score was found between the groups. CONCLUSIONS PIB for erector spinae plane block in video-assisted thoracic surgery resulted in a larger anaesthetised area and required a lower anaesthetic dose to maintain the analgesic effect. Therefore, it is more suitable for erector spinae plane block than continuous infusion.

Trials 2022; 23:792. [PMID: 36131308 PMCID: PMC9490991 DOI: 10.1186/s13063-022-06726-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/08/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Minimally invasive thoracic surgery (MITS) has been shown to reduce postoperative pain and contribute to better postoperative quality of life as compared to open thoracic surgery (Bendixen et al., Lancet Oncol 17:836-44, 2016). However, it still causes significant post-operative pain. Regional anaesthesia techniques including fascial plane blocks such as the erector spinae plane block (ESP) have been shown to contribute to post-operative pain control after MITS (Finnerty et al., Br J Anaesth 125:802-10, 2020). Case reports relating to ESP catheters have described improved quality of pain relief using programmed intermittent boluses (PIB) instead of continuous infusion (Bendixen et al., Lancet Oncol 17:836-44, 2016). It is suggested that larger, repeated bolus dose may provide superior pain relief, possibly because of improved spread of the local anaesthetic medications (Ilfeld and Gabriel, Reg Anesth Pain Med 44:285-86, 2019). Evidence for improved spread of local anaesthetic may be found in one study which demonstrated that PIB increased the spread of local anaesthetic medication compared to continuous infusions for continuous paravertebral blocks, which are another type of regional anaesthesia technique for the chest wall (Hida et al., Reg Anesth Pain Med 44:326-32, 2019). Similarly, regarding labour epidural analgesia, the weight of evidence is in favour of PIB providing better pain relief compared with continuous infusion (Onuoha, Anesthesiol Clin 35:1-14, 2017). Since fascial plane blocks, such as ESP, rely on the spread of local anaesthetic medication between muscle layers of the chest wall, intermittent boluses may be particularly useful for this group of blocks. However, until recently, pumps capable of providing automated boluses in addition to patient-controlled boluses were not widely available. To best of our knowledge, there are no randomised controlled trials comparing continuous infusion versus intermittent bolus strategies for erector spinae plane block for MITS in terms of patient centred outcomes such as quality of recovery. METHODS This trial will be a prospective, double-blinded, randomised controlled superiority trial. A total of 60 eligible patients will be randomly assigned to receive an intermittent bolus regime of local anaesthetic vs a continuous infusion of local anaesthetic. The medication will be delivered via an ultrasound-guided erector spinae plane block catheter which will be inserted by an anaesthesiologist while the patient is under general anaesthetic before their MITS surgery begins. The primary outcome being measured is the Quality of Recovery (QoR-15) score between the two groups 24 h after surgery. Secondary outcomes include respiratory testing of maximal inspiratory volume measured with a calibrated incentive spirometer, area under the curve for Verbal Rating Score for pain at rest and on deep inspiration versus time over 48 h, total opioid consumption over 48 h, QoR-15 score at 48 h and time to first mobilisation. DISCUSSION Despite surgical advancements in thoracic surgery, severe acute post-operative pain following MITS is still prevalent. This study will provide new knowledge and possible recommendations about the efficacy of programmed intermittent bolus regimen of local anaesthetic vs a continuous infusion of local anaesthetic via an ultrasound-guided erector spinae plane catheter for patients undergoing MITS.

Abstract
BACKGROUND Continuous thoracic paravertebral block (TPVB) connected with patient-controlled analgesia (PCA) pump is an effective modality to reduce postoperative pain following thoracic surgery. For the PCA settings, the programmed intermittent bolus infusion (PIBI) and continuous infusion (CI) are commonly practiced. However, the comparative effectiveness between the 2 approaches has been inconsistent. Thus, the aim of this study was to explore the optimal PCA settings to treat postthoracotomy pain by combing PIBI and CI together. METHODS All enrolled patients undergoing thoracoscopic surgery accepted ultrasound-guided TPVB catheterization before the surgery and then were randomly allocated in to 3 groups depending on different settings of the PCA pump connecting to the TPVB catheter: the PIBI+CI, PIBI, and CI groups. Numerical Rating Scales were evaluated for each patient at T1 (1 h after extubation), T2 (12 h after the surgery), T3 (24 h after the surgery), T4 (36 h after the surgery), and T5 (48 h after the surgery). Besides, the consumptions of PCA ropivacaine, the number of blocked dermatomes at T3, and the requirement for extra dezocine for pain relief among the 3 groups were also compared. RESULTS First, the Numerical Rating Scale scores in the PIBI+CI group were lower than the CI group at T2 and T3 (P<0.05) when patients were at rest and were also lower than the CI group at T2, T3, and T4 (P<0.01) and the PIBI group at T3 when patients were coughing (P<0.01). Second, the 2-day cumulative dosage of PCA in the PIBI+CI group was lower than both the CI and PIBI groups (P<0.01). Third, the number of blocked dermatomes in the PIBI and PIBI+CI groups were comparable and were both wider than the CI group at T3 (P<0.01). Finally, a smaller proportion (not statistically significant) of patients in the PIBI+CI group (5.26%, 2/38) had required dezocine for pain relief when compared with the PIBI group (19.44%, 7/36) and the CI group (15.79%, 6/38). CONCLUSIONS The combination of PIBI and CI provides superior analgesic modality to either PIBI or CI alone in patients undergoing thoracoscopic surgery. Therefore, it should be advocated to improve the management of postoperative pain, clinical outcomes, and ultimately patient satisfaction.

Abstract
Video‐assisted thoracoscopic surgery has become increasingly popular due to faster recovery times and reduced postoperative pain compared with thoracotomy. However, analgesic regimens for video‐assisted thoracoscopic surgery vary significantly. The goal of this systematic review was to evaluate the available literature and develop recommendations for optimal pain management after video‐assisted thoracoscopic surgery. A systematic review was undertaken using procedure‐specific postoperative pain management (PROSPECT) methodology. Randomised controlled trials published in the English language, between January 2010 and January 2021 assessing the effect of analgesic, anaesthetic or surgical interventions were identified. We retrieved 1070 studies of which 69 randomised controlled trials and two reviews met inclusion criteria. We recommend the administration of basic analgesia including paracetamol and non‐steroidal anti‐inflammatory drugs or cyclo‐oxygenase‐2‐specific inhibitors pre‐operatively or intra‐operatively and continued postoperatively. Intra‐operative intravenous dexmedetomidine infusion may be used, specifically when basic analgesia and regional analgesic techniques could not be given. In addition, a paravertebral block or erector spinae plane block is recommended as a first‐choice option. A serratus anterior plane block could also be administered as a second‐choice option. Opioids should be reserved as rescue analgesics in the postoperative period.

Anaesth Crit Care Pain Med 2021; 40:100952. [PMID: 34560315 DOI: 10.1016/j.accpm.2021.100952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 06/08/2021] [Accepted: 07/28/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Thoracic paravertebral block (TPVB) is effective for analgesia for unilateral thoracic surgery. However, since the paravertebral space is highly vascular, injection of local anaesthetics into the paravertebral space may induce systemic local anaesthetic toxicity. We examined the effect of addition of epinephrine to paravertebral levobupivacaine on its plasma concentration. METHODS In a randomised single blind trial, twenty-four male patients who were scheduled to undergo elective unilateral pulmonary lobectomy or segmentectomy under general anaesthesia combined with TPVB were enrolled in this study. They were randomly divided into two groups: one group received a single bolus thoracic paravertebral injection of 1 mg/kg of 0.25% levobupivacaine with 5 μg/mL epinephrine and the other group received a single bolus thoracic paravertebral injection of 1 mg/kg of 0.25% levobupivacaine alone. Arterial blood samples were obtained for plasma levobupivacaine assay after injection. The peak plasma concentration (Cmax) and the time to peak plasma concentration (Tmax), for levobupivacaine were calculated. RESULTS There were no significant differences in patients' characteristics between the two groups. The mean arterial Cmax values of levobupivacaine were 0.48 ± 0.11 μg/mL with epinephrine and 0.71 ± 0.31 μg/mL without epinephrine (P = 0.041). The mean arterial Tmax values of levobupivacaine were 46.0 ± 35.6 min with epinephrine and 12.0 ± 7.2 min without epinephrine (P = 0.005). CONCLUSION The addition of 5-μg/mL epinephrine to a single bolus thoracic paravertebral injection of 1-mg/kg levobupivacaine significantly decreased Cmax and delayed Tmax of levobupivacaine. The addition of epinephrine to levobupivacaine may be a useful strategy to reduce systemic levobupivacaine toxicity. CLINICAL TRIAL REGISTRATION NUMBER UMIN 000021942.

J Clin Anesth 2021; 75:110489. [PMID: 34481363 DOI: 10.1016/j.jclinane.2021.110489] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 08/11/2021] [Accepted: 08/16/2021] [Indexed: 10/20/2022]
Abstract
STUDY OBJECTIVE A lateral mini-thoracotomy approach to cardiac surgery causes severe and complicated postoperative pain compared to the sternotomy approach. In this study we assessed the benefits and risks of intermittent bolus erector spinae plane block (ESPB) via a catheter for patients who underwent cardiac surgery through a lateral mini-thoracotomy. DESIGN A propensity score-matched retrospective cohort study. SETTING University hospital. PATIENTS 452 consecutive patients that underwent cardiac surgery through a lateral mini-thoracotomy from 2018 to 2020. INTERVENTIONS Patients who received intermittent bolus ESPB through a catheter for 3 days (ESPB group, n = 93) were compared with patients who did not receive any regional anesthesia (Control group, n = 174) after propensity score matching. MEASUREMENTS The primary endpoint was postoperative in-hospital cumulative opioid consumption (calculated as oral morphine milligram equivalents, MME). The secondary outcomes were intraoperative sufentanil doses, therapeutic use of antiemetic, pulmonary infection (assessed using a modified clinical pulmonary infection score, CPIS), durations of ICU and hospital stays, and ESPB related/unrelated complications. MAIN RESULTS There is a lower oral MME in the ESPB group, 266 ± 126 mg in the ESPB group vs. 346 ± 105 mg in the control group (95% CI -113 to -46; P < 0.01). Fewer patients received therapeutic antiemetic agents in the ESPB group (30% vs. 42%, odds ratio 0.58; 95% CI 0.34 to 0.99; P = 0.04). The modified CPIS in the ESPB group is lower: 1.4 ± 0.9 vs. 2.0 ± 1.0 (95% CI -0.9 to -0.3; P < 0.01) on postoperative day 1; 1.6 ± 0.9 vs. 2.0 ± 0.9 (95% CI -0.7 to -0.2; P < 0.01) on postoperative day 2. The observed complications associated with ESPB include pneumothorax (1%), staxis around stomas (5%), hypotension (1%), catheter displacement (3%), and catheter obstruction (2%). None of the patients had any adverse outcomes. CONCLUSION Intermittent bolus ESPB is relatively safe and correlated with a reduction in the use of opioids and antiemetics for cardiac surgery through a lateral mini-thoracotomy.

Bilateral continuous erector spinae plane block using a programmed intermittent bolus regimen versus intrathecal morphine for postoperative analgesia in living donor laparoscopic hepatectomy: A randomized controlled trial. J Clin Anesth 2021; 75:110479. [PMID: 34455152 DOI: 10.1016/j.jclinane.2021.110479] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 07/29/2021] [Accepted: 07/30/2021] [Indexed: 11/20/2022]
Abstract
STUDY OBJECTIVE To determine if continuous bilateral erector spinae plane (ESP) blocks would improve the postoperative analgesia in the first 48 h after laparoscopic donor hepatectomy, compared to intrathecal morphine (ITM). DESIGN Prospective, randomized controlled trial. SETTING A single tertiary care center from October 2019 and September 2020. PATIENTS A total of 60 donors scheduled to undergo elective laparoscopic right hepatectomy. INTERVENTIONS Sixty donors were randomized to receive either bilateral continuous T8 ESP blocks with a programmed intermittent bolus regimen of 10 mL 0.2% ropivacaine every 3 h for 48 h (n = 30) or 400 μg ITM (n = 30), in addition to IV fentanyl PCA and multimodal analgesia. MEASUREMENTS The primary outcome was cumulative opioid consumption over the first 48 h, expressed as IV morphine equivalents. Secondary outcomes included pain scores, Quality of Recovery-15 scores, ambulation within 24 h, time to first flatus, and opioid-related adverse drug events over 72 h. MAIN RESULTS Fifty-nine donors were analyzed. Cumulative 48-h opioid consumption was similar between the ITM and ESP groups (29.8 ± 18.2 vs. 35.1 ± 21.9 mg, mean difference (ESP-ITM) (95% CI), 5.3 (-11.5 to 22) mg; p > 0.99). Resting pain scores at 48 and 72 h postoperatively were significantly lower in the ESP group (0 [0-2] vs. 3 [1.5-3], and 0 [0-2] vs. 3 [1-3] respectively, both p<0.001) (Goldaracena and Barbas, 2019; Ko et al., 2009; Choi et al., 2007 [1-3]) respectively, both p < 0.001). The ESP group had significantly lower incidences of postoperative nausea, vomiting, and pruritus at all timepoints. There were no differences in recovery outcomes. CONCLUSIONS Continuous ESP blocks did not reduce cumulative 48-h opioid consumption compared to 400 μg ITM after laparoscopic donor hepatectomy, but it was associated with a significantly reduced risk of postoperative nausea, vomiting and pruritus.

Abstract
BACKGROUND Regional analgesic techniques such as paravertebral blocks (PVBs) have been popularized for analgesia following video-assisted thoracoscopic surgery (VATS). In this single center retrospective propensity matched cohort of subjects, we investigate the impact of paravertebral blocks on the analgesic and non-analgesic outcomes. METHODS Institutional database was queried to identify all patients undergoing VATS between January 2013 and July 2019 and these patients were divided into those who received paravertebral blocks in combination with general anesthesia (GA) [PVB group] and those who received GA without paravertebral blocks [GA group]. Propensity score matching based on common patient confounders were used to identify patients in each group. Primary outcomes of the study were average pain scores and opioid consumption in the first 24 hours. Secondary analgesic outcomes included pain scores and opioid requirements at other timepoints over the first 48 hours. Non analgesic outcomes were obtained from STS General Thoracic Surgery Database and included length of hospital stay, need for ICU admission, composite outcome of any complication during the hospital course and 30-day mortality. Exploratory analyses were conducted to investigate the impact of PVB on analgesia following different types of surgery and as to whether any other covariates had a greater influence on the included patient centered outcomes. MAIN RESULTS After propensity score matching, a total of 520 patients (260 per group) were selected for the study out of 1095 patients. The opioid consumption in terms of oral morphine milligram equivalent (MME) [Median (IQR)] for the first 24 hours was significantly lower with the use of PVB [PVB group- 78.5 (96.75); GA group-127.0 (111.5); p<0.001] while the average pain scores in the first 24 hours did not differ significantly [PVB group-4.71 (2.28); GA group-4.85 (2.30); p = 0.70]. The length of hospital stay, opioid requirements at other timepoints, need for ICU admission in the immediate post-operative period and the composite outcome-'any complication' (35% vs 48%) were significantly lower with the use of PVB. Subgroup analysis showed a longer duration of benefit following major lung surgeries compared to others. CONCLUSION Paravertebral blocks reduced the length of stay and opioid consumption up to 48 hours after VATS without significantly impacting pain scores.

Abstract
BackgroundDespite the popularity of continuous thoracic paravertebral block (TPVB), there is a paucity of information on catheter tip position and distribution of injectate through the catheter. We observed, in real time, the spread of dye, the catheter tip position and sensory block levels produced with three different (intercostal (IC), transverse process sagittal (TS) and paralaminar (PL)) approaches to ultrasound-guided TPVB in patients undergoing video-assisted thoracoscopic surgery.MethodsAfter the induction of general anesthesia, ultrasound-guided TPVB was conducted with a patient in the lateral decubitus position. During surgery, 10 mL of dye was injected through a catheter to observe the catheter tip and the dye distribution under thoracoscopy. Dermatomal sensory block levels were measured postoperatively.ResultsTen patients for each of three different approaches completed the study. There were a variety of dye spreading patterns. The median (range) number of segmental levels stained with dye was 1.5 (1–4), 3 (1–4) and 3 (1–5) with the IC, TS and PL approaches, respectively. We observed that a catheter tip was present at the same segmental paravertebral space as intended in 50%–90% of patients using these approaches. The median (range) number of dermatomes with sensory blockade at 6 hours after block was 2.5 (1–4), 3 (2–8) and 3 (1–8) with the IC, TS and PL approaches, respectively.ConclusionsAlthough a bolus injection through a catheter for ultrasound-guided TPVB produced multiple levels of spread and sensory blockade in more than half the patients, considerable differences existed in the spread regardless of approach.

Abstract
There are numerous possible techniques for delivering local anaesthetic through peripheral nerve catheters. These include continuous infusions, patient-controlled boluses and programmed intermittent boluses. The optimal delivery regimen of local anaesthetic is yet to be conclusively established. In this review, we identified prospective trials of delivery regimens through peripheral nerve catheters. Our primary outcome was visual analogue scale scores for pain at 48 h. Secondary outcomes were: visual analogue scores at 24 h; patient satisfaction scores; rescue opioid use; local anaesthetic consumption; and nausea and vomiting. Network meta-analysis was used to compare these outcomes. Predefined sub-group analyses were performed. Thirty-three studies enrolling 1934 participants were included. In comparison with continuous infusion, programmed intermittent boluses improved visual analogue pain scores at both 48 and 24 h, the weighted mean difference (95%CI) being -0.63 (-1.12 to -0.14), p = 0.012 and -0.48 (-0.92 to -0.03), p = 0.034, respectively. Programmed intermittent boluses also improved satisfaction scores, the weighted mean difference (95%CI) being 0.70 (0.10-1.31), p = 0.023, and reduced rescue opioid use, the weighted mean difference (95%CI) in oral morphine equivalent at 24 h being -23.84 mg (-43.90 mg to -3.77 mg), p = 0.020. Sub-group analysis revealed that these findings were mostly confined to lower limb and truncal catheter studies; there were few studies of programmed intermittent boluses for upper limb catheters. Programmed intermittent boluses may provide optimal delivery of a local anaesthetic through peripheral nerve catheters. Further research is warranted, particularly to delineate the differences between upper and lower limb catheter locations, which will help clarify the clinical relevance of these findings.

Abstract
Single injections in the anterior region of the thoracic paravertebral space (TPVS) have been reported to generate a multisegmental longitudinal spreading pattern more frequently than those in the posterior region of the TPVS. In this trial, we examined the hypothesis that a continuous thoracic paravertebral block (TPVB) administered through a catheter inserted into the anterior region of the TPVS allows a wider sensory block dispersion. Fifty consecutive patients undergoing video-assisted thoracic surgery were enrolled. Before the surgery, an infusion catheter was inserted into the TPVS through a needle placed adjacent to either the parietal pleura (group A) or internal intercostal membrane (group P) using an ultrasound-guided intercostal transverse approach according to a randomized allocation schedule. A chest radiograph was obtained postoperatively after injection of 10 mL of radiopaque dye through the catheter. Thereafter, 20 mL of 0.375% levobupivacaine was injected via the catheter, followed by commencement of continuous TPVB with 0.25% levobupivacaine at 8 mL/h. The primary outcome was the number of blocked dermatomes at 24 h after surgery. The secondary outcomes included radiopaque dye spreading patterns, the number of segments reached by the radiopaque dye, the number of blocked dermatomes at 2 h after surgery, and pain scores. The median (interquartile range [range]) number of blocked dermatomes 24 h after surgery was 3 (2.75–4 [1–6]) in group A (n = 22) and 2 (1.5–3 [0–7]) in group P (n = 25; p = 0.037). No significant differences in the other outcomes were found between the groups. In conclusion, a continuous TPVB administered using a catheter supposedly inserted into the anterior region of the TPVS allows a wider sensory block dispersion than a catheter inserted into the posterior region of the TPVS. This trial is registered with the UMIN Clinical Trials Registry (UMIN000018578).
