OBJECTIVE: The mid point-transverse process to pleura block (MTPB) is a new variant of thoracic paravertebral block (TPVB). This study aimed to compare TPVB and MTPB with respect to intraoperative attenuation of the hemodynamic stress response to surgery and postoperative analgesia in pediatric open heart surgery with midline sternotomy.
METHODS: A single-center, randomized, controlled, double-blind, non-inferiority study.
METHODS: Tertiary care children\'s university hospital.
METHODS: We recruited 83 children aged 2-12 years of both sexes with American Society of Anesthesiologists (ASA) physical status class II who were scheduled for elective open cardiac surgeries with midline sternotomy for the repair of simple noncyanotic congenital heart defects.
METHODS: Eligible participants were randomized into either the TPVB or MTPB groups at a ratio of 1:1. In the TPVB group, patients were bilaterally injected with 0.4 ml/kg of 0.25% bupivacaine in the paravertebral space at T4 and T5. In the MTPB group, patients were bilaterally injected with 0.4 ml/kg of 0.25% bupivacaine mid-transverse process and pleura just posterior to superior costotransverse ligament at the level of T4 and T5.
METHODS: The primary outcome was the hemodynamic responses to sternotomy incision, including heart rate (HR) and invasive mean arterial pressure (MAP), recorded before and after the induction of anesthesia, after skin incision, after sternotomy, 15 min after cardiopulmonary bypass (CPB), and after the closure of the sternum. The secondary outcomes were time needed to perform the bilateral block, intraoperative fentanyl consumption, postoperative fentanyl consumption, modified objective pain score (MOPS) measured at 1, 2, 6, 12, 18, and 24 h after extubation, extubation time, intensive care unit (ICU) discharge time, and the incidence of non-surgical complications (postoperative pruritus, postoperative vomiting, pneumothorax, hematoma or local anesthetic toxicity).
RESULTS: There were no significant differences in HR and MAP in the TPVB group compared with the MTPB group at the following time points: baseline, after induction, after skin incision, after sternotomy, 15 min after CPB, and after sternal closure. Intergroup comparisons of HR and MAP did not reveal significant differences between the groups. The median (IQR) time needed to perform bilateral MTPB (7[6-8] min) was significantly (p < 0.001) shorter than that of TPVB (12[10-13] min). Intraoperative fentanyl consumption and fentanyl consumption in the first postoperative 24 h after extubation were similar in the TPVB and MTPB groups (4[2-4] vs 4[2-4] and 4.66 ± 0.649 vs 4.88 ± 1.082 μg/kg), respectively. Extubation time and ICU discharge time were comparable in the TPVB and MTPB groups (2[1-3] vs 2[1-3] h and 21.2 ± 2.5 vs 20.8 ± 2.6 h), respectively. Measurements of MOPS pain scores at 1, 2, 6, 12, 18, and 24 h after extubation were similar in both groups. The incidence of nonsurgical complications was similar in both groups.
CONCLUSIONS: MTPB is non-inferior to TPVB in attenuating the intraoperative hemodynamic stress response to noxious surgical stimuli and in reducing perioperative opioid consumption, extubation time, and ICU discharge time. Moreover, MTPB is technically easier than TPVB and requires less time to perform. Clinical trial registration number The clinical trial registration was prospectively performed at the Pan African Clinical Trials Registry (PACTR202204901612169, approval date 01/04/2022, URL https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=22602).

BACKGROUND: Regional analgesia techniques are crucial for pain management after cervical spine surgeries. Anesthesiologists strive to select the most effective and least hazardous regional analgesia technique for the cervical region. Our hypothesis is that an intermediate cervical plexus (IC) block can provide adequate postoperative analgesia compared to a cervical erector spinae (ES) block in patients undergoing anterior cervical spine surgery.
METHODS: In this double-blind prospective trial, 58 patients were randomly assigned into two equal groups prior to the administration of general anesthesia. Patients in the IC group (n = 29) underwent ultrasound-guided bilateral intermediate cervical plexus block with 15 ml of bupivacaine 0.25% administered to each side. The ES group (n = 29) underwent ultrasound-guided bilateral cervical erector spinae plane blocks with 15 ml of 0.25% bupivacaine administered to each side at the C6 level. The primary outcome was to record the time to the first call for rescue analgesia (nalbuphine), and the secondary outcomes were to measure the performance time, the onset of the sensory block, the intraoperative fentanyl consumption, postoperative pain intensity using VAS, the postoperative total nalbuphine consumption, and postoperative complications such as nausea, vomiting, hypotension, and bradycardia.
RESULTS: The performance and onset of sensory block times were significantly shorter in the IC group compared to the ES group. The time to first call for nalbuphine was significantly shorter in the IC group (7.31 ± 1.34 h) compared to the ES group (11.10 ± 1.82 h). The mean postoperative VAS scores were comparable between the two groups at the measured time points, except at 8 h, where it was significantly higher in the IC group, and at 12 h, where it was significantly higher in the ES group. The total nalbuphine consumption was significantly higher in the IC group (33.1 ± 10.13 mg) compared to the ES group (22.76 ± 8.62 mg).
CONCLUSIONS: For patients undergoing anterior cervical spine surgery, the intermediate cervical plexus block does not provide better postoperative regional analgesia compared to the cervical erector spinae block. Performance time and onset time were shorter in the IC group, whereas nalbuphine consumption was lower in the ES group.
BACKGROUND: The trial was registered at clinicaltrials.gov. (NCT05577559, and the date of registration: 13-10-2022).

BACKGROUND: Regional block, such as thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), or serratus anterior plane block (SAPB) has been recommended to reduce postoperative opioid use in recent guidelines, but the optimal options for intraoperative opioid minimization remain unclear. The aim of this study was to evaluate the intraoperative opioids-sparing effects of three regional blocks (TEA, TPVB, and SAPB) in patients undergoing video-assisted thoracoscopic surgery (VATs).
METHODS: This was a retrospective study of the adults undergoing VATs at a tertiary medical center between January 2020 and February 2022. According to the type of regional block used, patients were classified into 4 groups: GA group (general anesthesia without any regional block), TEA group (general anesthesia combined with TEA), TPVB group (general anesthesia combined with TPVB), and SAPB group (general anesthesia combined with SAPB). Cases were matched with a 1:1:1:1 ratio for analysis by age, sex, ASA physical status, and operation duration. The primary outcome was the total intraoperative opioid consumption standardized to Oral Morphine Equivalents (OME). Multivariable linear regression was used to estimate the association of the three regional blocks with the OME.
RESULTS: A total of 2159 cases met the eligibility criteria. After matching, 168 cases (42 in each group) were included in analysis. Compared with GA without any reginal block, the use of TEA, TPVB, and SAPB reduced the median of intraoperative OME by 78.45 mg (95% confidence interval [CI], -141.34 to -15.56; P = 0.014), 94.92 mg (95% CI, -154.48 to -35.36; P = 0.020), and 11.47 mg (95% CI, -72.07 to 49.14; P = 0.711), respectively.
CONCLUSIONS: The use of TEA or TPVB was associated with an intraoperative opioid-sparing effect in adults undergoing VATs, whereas the intraoperative opioid-sparing effect of SAPB was not yet clear.

Lumbar plexus blocks (LPBs) are routinely employed for analgesia in hip fracture surgery; however, a novel regional technique, the pericapsular nerve group (PENG) block, potentially offers comparable pain reduction while preserving motor function. Patients aged 45-90 years who underwent hip fracture surgery were allocated to receive either a PENG block or an LPB for analgesia. The primary outcome was the incidence of quadriceps motor block (defined as the paresis or paralysis of the knee extension) at 12 h postoperatively. The secondary outcomes included the performance time, the time to first analgesic requirement, postoperative intravenous (IV) fentanyl consumption, the ability to undergo physiotherapy at 24 and 48 h, complications, sensory and motor block assessments, postoperative numeric rating scale (NRS) pain scores, and patient outcome questionnaires. There was a significantly lower incidence of quadriceps motor block at 6 h (26.7% vs. 80.0%; p < 0.001) and at 12 h (20.0% vs. 56.7%; p = 0.010). The PENG block provided better preservation of the sensory block as well as better performance time (p < 0.001) and time to first analgesia requirement (p = 0.034), whereas the LPB resulted in lower postoperative IV fentanyl consumption at 24 h (p = 0.013). The PENG block demonstrated superiority over the LPB in preserving quadriceps strength and patient satisfaction without any substantial complications, despite higher opioid consumption within the first 24 h post-surgery.

UNASSIGNED: The present study compared the surgical wound catheter (SWC), femoral nerve block (FNB), and adductor canal block (ACB) for postoperative analgesia after knee arthroplasty.
UNASSIGNED: The study included (180) patients scheduled for unilateral total knee replacement and were randomly allocated into three groups. Patients received postoperative analgesia via continuous infusion of ropivacaine 0.2% (10 ml bolus followed by continuous infusion of 5 ml/hour) through the SWC, FNB, or ACB groups. All groups received supplemental analgesia by IV morphine using patient controlled analgesia. Pain scores were assessed at rest and during movements, the worst and least pain scores, and how often were in worst pain during the first 72 hours. The functional activity and patient\'s satisfaction were also recorded.
UNASSIGNED: The study showed significant reductions in pain scores at rest and during movements in all groups compared to the baseline scores. Significant reductions in pain scores were observed in both ACB and FNB groups compared to the SWC group (P < 0.05). The worst pain scores were (6.15 ± 2.9, 5.85 ± 2.7, and 5.025 ± 1.513), least pain scores (2.06 ± 0.72, 1.92 ± 1.34 and 1.89 ± 1.76), percentage of time in worst pain (17.67 ± 9.15, 11.42 ± 7.50, and 9.8.8 ± 8.14) and the total morphine consumption (39.24 ± 6.82, 34.55 ± 7.86, and 26.40 ± 8.47 mg) in the SWC, FNB, and ACB groups, respectively. Functional assessments and patient\'s satisfaction, at 6 and 24 hours, were significantly better in ACB followed by SWC, and lastly FNB group (P < 0.5). No significant differences in the incidence of side effects (P > 0.05). Local anesthetic leak from the SWC was a continuous concern by the orthopedic surgeons.
UNASSIGNED: In terms of efficiency, ACB provided the highest quality of analgesia in terms of pain relief, functional activity, and patient\'s satisfaction. Both ACB and FNB provided higher quality of analgesia compared to the SWC. While ACB and SWC provided better functional improvements compared to FNB.

Anterior lumbar interbody fusion (ALIF) is a lumbar arthrodesis technique via an anterior approach that is less invasive than the posterior approaches. However, it is associated with specific pain in the abdominal wall.
The objective of this study was to determine whether performing a bilateral ultrasound-guided Transversus abdominis plane (TAP) block allows a reduction in morphine consumption in the first 24 hours after surgery.
This study is a prospective single-center, randomized, double-blind study.
Patients undergoing ALIF surgery were included and randomized into two groups. Both groups received a TAP block performed at the end of surgery with either ropivacaine or placebo.
The primary outcome measure was morphine consumption in the first 24 hours. The main secondary outcomes were immediate postoperative pain and opioid-related side effects.
Intra- and postoperative anesthesia and analgesia protocols where standardized. A bilateral ultrasound-guided TAP block was performed with 75 mg (in 15 mL) of ropivacaine per side or isotonic saline serum depending on their assignment group.
Forty-two patients were included in the study (21 per group). Morphine consumption at 24 hours (28 mg [18-35] in the ropivacaine group versus 25 mg [19-37] in the placebo group [p=.503]) were not significantly different between the two groups.
TAP block with ropivacaine or placebo provided a similar postoperative analgesia when associated with a multimodal analgesia protocol for ALIF.

Background Severe postoperative pain and immobility increase the length of hospital stay and immobility-related life-threatening complications after total hip replacement (THR). Pericapsular nerve group (PENG) block is a recent addition to pain management of neck of femur (NoF) fracture, the use of which has been incorporated into THR as alternative analgesia or as an adjunct with other regional analgesia techniques. The present study primarily aims to assess postoperative mobility. Secondary outcomes measured were the length of hospital stay, pain score, opioid consumption, and side effects. Methods This is a retrospective study of 50 patients who underwent primary THR. Twenty-eight patients received PENG block after spinal anesthesia (PENG Group), seven patients had general anesthesia (GA) with patient-controlled analgesia (PCA) postoperatively (PCA Group), and the remaining 15 received spinal anesthesia with fascia iliaca block (FIB Group). Mobilization was attempted in all patients (ability to stand and walk a few steps with a walker) 10 hours after the end of surgery. Data was collected for average postoperative pain score, time of mobilization, total opioid consumption (till discharge from the hospital), opioid-related side effects, and time of discharge. Results Mobilization was attempted in all patients 10 hours after the end of the surgery, irrespective of their anesthetic technique. In the PENG Group, 26 patients (n=28) could be mobilized after the first 10 hours without opioids. The total morphine requirement until discharge was significantly less in the PENG Group of patients compared to the FIB and GA+PCA patients. The average time of discharge (hours) from the hospital (22.1+/-4.9) was also significantly lower in the PENG Group compared to all other groups (31.7 +/- 3.4, p=<0.01). The average postoperative pain score was significantly low in the PENG Group within the first 48 hours. Conclusion The PENG block helps in early mobilization and enhanced recovery after THR.

BACKGROUND: The PEricapsular Nerve Group (PENG) block is a novel regional analgesia technique that provides improved analgesia in patients undergoing hip surgery while preserving motor function. In this study the PENG block was investigated for analgesia in elective total hip arthroplasty (THA).
METHODS: In this multi-centre double-blinded randomized-controlled trial, in addition to spinal anesthesia and local infiltration analgesia (LIA), THA patients received either a PENG block or a sham block. The primary outcome was pain score (numeric rating scale 0-10) 3 h postoperatively (Day 0). Secondary outcomes were postoperative quadriceps muscle strength, postoperative Day 1 pain scores, opiate use, complications, length of hospital stay, and patient-reported outcome measures.
RESULTS: Sixty patients were randomized and equally allocated between groups. Baseline demographics were similar. Postoperative Day 0, the PENG group experienced less pain compared to the sham group (PENG: 14 (47%) patients no pain, 14 (47%) mild pain, 2 (6%) moderate/severe pain versus sham: 6 (20%) no pain, 14 (47%) mild pain, 10 (33%) moderate/severe pain; p = 0.03). There was no difference in quadriceps muscle strength between groups on Day 0 (PENG: 23 (77%) intact versus sham: 24 (80%) intact; p = 0.24) and there were no differences in other secondary outcomes.
CONCLUSIONS: Patients receiving a PENG block for analgesia in elective THA experience less postoperative pain on Day 0 with preservation of quadriceps muscle strength. Despite these short-term benefits, no quality of recovery or longer lasting postoperative effects were detected.

UNASSIGNED: We aimed to explore the impact of opioid-sparing anesthesia on patients\' quality of recovery after video-assisted thoracoscopic surgery (VATS). We tested the primary hypothesis that our predefined opioid-sparing anesthesia provides better quality of patients\' recovery compared to routine anesthesia in VATS.
UNASSIGNED: Patients between 18 and 70 years, scheduled for elective VATS, had an American Society of Anesthesiologists (ASA) class I-III under general anesthesia, were randomly allocated to: routine anesthesia group and opioid-sparing anesthesia group. Patients in the opioid-sparing anesthesia group were mainly given preoperative thoracic paravertebral blockade with intraoperative withholding longer acting opioids. Patients in routine anesthesia group received opioid-based anesthesia. The primary outcome was the Quality of Recovery-15 scale (QoR-15) at 6 hours after surgery. The secondary outcomes included QoR-15 at 24 and 48 hours after surgery, Overall Benefit of Analgesia Score Satisfaction with pain treatment (OBAS) and acute pain intensity at 6, 24 and 48 hours after surgery, and clinical outcomes of recovery after surgery.
UNASSIGNED: A total of 159 patients were included in final analysis. The median difference in QoR-15 between opioid-sparing anesthesia and routine anesthesia was 4 (95% CI: 1-6) at 6 hours, 8 (95% CI: 4-12) at 24 hours and 4.7 (95% CI: 1-6) at 48 hours after surgery respectively; 73.4% of patient showed good recovery in opioid-sparing anesthesia group, compared to 53.8% in routine anesthesia group at 24 hours after surgery (P=0.01). Patients demonstrated lower OBAS in opioid-sparing anesthesia group compared to routine anesthesia at all time points after surgery (P<0.05). The pain at most was significantly lower in opioid-sparing anesthesia group compared to routine anesthesia at 6 and 48 hours after surgery (P<0.05). Patients exhibited faster recovery with opioid-sparing anesthesia on time to mobilize and time to first flatus (P<0.01).
UNASSIGNED: Our intraoperative opioid-sparing anesthesia cannot improve patients\' recovery at 6 hours after VATS lung surgery, but it demonstrates better outcomes at 24 hours after surgery compared to routine anesthesia, reaching to a clinically important difference.
UNASSIGNED: This study is registered in the Chinese Clinical Trial Registry, ChiCTR2000031609.

The purpose of this study is to assess the feasibility and the perioperative outcomes of laparoscopic gynecological surgery in regional anesthesia (RA) from the point of view of the surgeon, anesthesiologist and patient. This is a prospective cohort study comprising sixty-six women planned to undergo gynecologic laparoscopy surgery for benign pathology at tertiary care gynecolgical center of the University Federico II of Naples. Women were assigned, according to their preference, to either RA (Group A) or general anesthesia (GA) (Group B). Surgical, anesthesiologic and postoperative recovery data were recorded. Postoperative pain was considered as the primary outcome. Secondary outcomes included mobilization, length of hospital stay, global surgeons and patient satisfaction, intraoperative pain assessment in Group A. Immediate postoperative pain was significantly lower in Group A 0 vs 2 (p < 0.001), with no significant differences at 24 h. The secondary outcome demonstrated early patient\'s mobilization (p < 0.001) as well as early discharge (p < 0.001) and greater patient\'s satisfaction for the Group A. In these patients, a maximum pain score of 3 points out of 5 was recorded through the entire surgery. RA showed to decrease the impact of surgical stress and to guarantee a quicker recovery without compromising surgical results. Although several surgical approaches can be employed to treat different conditions, RA technique could be a viable option for well-selected patients affected by gynecological diseases.
