UNASSIGNED: Multimodal analgesia plays a key role in enhanced recovery after surgery. Herein, we describe a trial protocol investigating the effects of oxycodone-vs. sufentanil-based patient-controlled analgesia in combination with quadratus lumborum block (QLB) vs. transverse abdominis plane block (TAPB) on quality of recovery following major laparoscopic gastrointestinal surgery.
UNASSIGNED: and analysis: This is a prospective, randomized, controlled clinical trial with a 2 × 2 factorial design. A total of 120 adult patients undergoing laparoscopic major gastrointestinal surgery will be randomized, in a 1:1:1:1 ratio, to receive one of two patient-controlled analgesia regimens (based on oxycodone or sufentanil) and one of two regional blocks (QLB or TAPB). The primary outcome measure of this trial is the quality of recovery at 24 h after surgery, assessed using the 15-item quality of recovery (QoR-15) scale. The secondary outcomes include QoR-15 scores at 48 and 72 h after surgery; visceral and incisional pain at rest and while coughing at 1, 6, 24 and 48 h postoperatively; analgesic consumption within 0-24 h and 24-48 h postoperatively; need for rescue analgesia; postoperative flatus time; postoperative adverse events (sedation, nausea and vomiting, use of antiemetics, respiratory depression, and dizziness); and length of postoperative hospital stay.
UNASSIGNED: The results of this trial will provide evidence for the optimal multimodal analgesic strategy to improve the quality of recovery for patients undergoing laparoscopic major gastrointestinal surgery.
UNASSIGNED: This trial was registered at the Chinese Clinical Trial Registry (www.chictr.org.cn, identifier: ChiCTR2400080766).

BACKGROUND: Despite pain being the most common reason for patients to visit the emergency department (ED), conventional pain management methods are often inadequate. Patient controlled analgesia (PCA), which allows patients to self-administer intravenous analgesia, is widely used across many hospital wards, however, is not routinely used in ED. We aimed to identify clinicians\' perceptions of PCA use in the ED setting.
METHODS: A qualitative descriptive approach was employed using semi-structured individual interviews conducted with ED clinicians from two hospitals in Western Australia. Interviews were recorded and transcribed. Data was analysed using qualitative content analysis.
RESULTS: Data saturation was achieved after 20 participant interviews. Five themes emerged from the interview data: sustainability and choosing the right patient; time; safety concerns and side effects; anticipating the patient\'s perspective (staff perception); facilitating PCA use in ED.
CONCLUSIONS: Most participants perceived that patients would experience several benefits from PCA use in ED. Several perceived barriers and facilitators were also identified. To facilitate the use of PCA in ED, there is a need for staff education on PCA use, patient selection guidelines and effective change management strategies. Further research about the time it takes to administer analgesia via PCA compared with conventional methods is needed.

UNASSIGNED: Intrathecal morphine (ITM) or erector spinae plane (ESP) block reduces postsurgical pain in patients who underwent kidney transplantation surgeries. We aimed to compare the effectiveness of both modalities in terms of duration and quality of postoperative analgesia along with postoperative fentanyl consumption.
UNASSIGNED: We conducted a randomised study and analysed 60 patients posted for elective live-related kidney transplantation surgery. They were randomised into two groups. Group M patients received ITM, whereas Group E patients received ESP block. We standardised the postoperative analgesia for both groups with intravenous fentanyl-based patient-controlled analgesia. The primary outcome was to compare the quality of analgesia using the numerical rating scale score between the groups. The secondary outcome was to observe the effect of both modalities on the duration of analgesia, postoperative fentanyl consumption, rescue analgesics requirement, catheter-related bladder discomfort and any complications.
UNASSIGNED: We found significantly lower pain scores at rest and while coughing in Group M at all time intervals, except at 24 h while coughing. The mean time to first analgesia requirement was significantly longer in Group M than in Group E (P = 0.002). No significant difference was found in postoperative consumption of total fentanyl (P = 0.065) and rescue analgesia in both groups. In Group M, there was significantly more nausea, vomiting and pruritus (P = 0.001).
UNASSIGNED: ITM provides long-lasting postoperative analgesia at the cost of higher side effects than ESP block.

UNASSIGNED: Oxycodone is a potent μ- and κ-opioid receptor agonist that can relieve both somatic and visceral pain. We assessed oxycodone- vs sufentanil-based multimodal analgesia on postoperative pain following major laparoscopic gastrointestinal surgery.
UNASSIGNED: In this randomised double-blind controlled trial, 40 adult patients were randomised (1:1, stratified by type of surgery) to receive oxycodone- or sufentanil-based multimodal analgesia, comprising bilateral transverse abdominis plane blocks, intraoperative dexmedetomidine infusion, flurbiprofen axetil, and oxycodone- or sufentanil-based patient-controlled analgesia. The co-primary outcomes were time-weighted average (TWA) of visceral pain (defined as intra-abdominal deep and dull pain) at rest and on coughing during 0-24 h postoperatively, assessed using the numerical rating scale (0-10) with a minimal clinically important difference of 1.
UNASSIGNED: All patients completed the study (median age, 64 years; 65% male) and had adequate postoperative pain control. The mean (SD) 24-h TWA of visceral pain at rest was 1.40 (0.77) in the oxycodone group vs 2.00 (0.98) in the sufentanil group (mean difference=-0.60, 95% CI, -1.16 to -0.03; P=0.039). Patients in the oxycodone group had a significantly lower 24-h TWA of visceral pain on coughing (2.00 [0.83] vs 2.98 [1.26]; mean difference=-0.98, 95% CI, -1.66 to -0.30; P=0.006). In the subgroup analyses, the treatment effect of oxycodone vs sufentanil on the co-primary outcomes did not differ in terms of age (18-65 years or >65 years), sex (female or male), or type of surgery (colorectal or gastric). Secondary outcomes (24-h TWA of incisional and shoulder pain, postoperative analgesic usage, rescue analgesia, adverse events, and patient satisfaction) were comparable between groups.
UNASSIGNED: For patients undergoing major laparoscopic gastrointestinal surgery, oxycodone-based multimodal analgesia reduced postoperative visceral pain in a statistically significant but not clinically important manner.

UNASSIGNED: Transcutaneous Electrical Acupoint Stimulation (TEAS) therapy opens up the possibility for individuals with Cancer-induced bone pain (CIBP) to receive a home-based, patient-controlled approach to pain management. The aim of this study is designed to evaluate the efficacy of patient-controlled TEAS (PC-TEAS) for relieving CIBP in patients with non-small cell lung cancer (NSCLC).
UNASSIGNED: This is a study protocol for a prospective, triple-blind, randomized controlled trial. We anticipate enrolling 188 participants with NSCLC bone metastases who are also using potent opioid analgesics from 4 Chinese medical centers. These participants will be randomly assigned in a 1:1 ratio to either the true PC-TEAS or the sham PC-TEAS group. All participants will receive standard adjuvant oncology therapy. The true group will undergo patient-controlled TEAS intervention as needed, while the sham group will follow the same treatment schedule but with non-conductive gel patches. Each treatment course will span 7 days, with a total of 4 courses administered. There will be 4 assessment time points: baseline, the conclusion of weeks 4, 8, and 12. The primary outcome of this investigation is the response rate of the average pain on the Brief Pain Inventory (BPI) scale at week 4 after treatment. Secondary outcomes include pain related indicators, quality of life scale, mood scales, and routine blood counts on the assessment days. Any adverse events will be promptly addressed and reported if they occur. We will manage trial data using the EDC platform, with a data monitoring committee providing regular quality oversight.
UNASSIGNED: PC-TEAS interventions offer an attempt to achieve home-based acupuncture treatment and the feasibility of achieving triple blinding in acupuncture research. This study is designed to provide more rigorous trial evidence for the adjuvant treatment of cancer-related pain by acupuncture and to explore a safe and effective integrative medicine scheme for CIBP.
UNASSIGNED: ClinicalTrials.gov NCT05730972, registered February 16, 2023.

This study aimed to compare the analgesic effects of programmed intermittent epidural boluses (PIEB) and continuous epidural infusion (CEI) for postoperative analgesia after elective cesarean section (CS).
Seventy-four women who underwent elective CS were randomized to receive either PIEB or CEI. The PIEB group received 4 ml-intermittent boluses of 0.11% ropivacaine every hour at a rate of 120 ml/h. The CEI group received a constant rate of 4 ml/h of 0.11% ropivacaine. The primary outcome was the pain score at rest at 36 h after CS. Secondary outcomes included the pain scores during mobilization, time-weighted pain scores, the incidence of motor blockade, and complications-related epidural analgesia during 36 h after CS.
The pain score at rest at 36 h after CS was significantly lower in the PIEB group compared with that in the CEI group (3.0 vs. 0.0; median difference: 2, 95% CI [1, 2], P < 0.001). The mean time-weighted pain scores at rest and during mobilizations were also significantly lower in the PIEB group than in the CEI group (pain at rest; mean difference [MD]: 37.5, 95% CI [24.6, 50.4], P < 0.001/pain during mobilization; MD: 56.6, 95% CI [39.8, 73.5], P < 0.001). The incidence of motor blockade was significantly reduced in the PIEB group compared with that in the CEI group (P < 0.001).
PIEB provides superior analgesia with less motor blockade than CEI in postpartum women after CS, without any apparent adverse events.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

UNASSIGNED: Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that can provide analgesia in the hemithorax, shoulder, and back of the neck. This study aimed to evaluate the post-operative analgesic effect of SPSIPB in patients undergoing video-assisted thoracoscopic surgery (VATS).
UNASSIGNED: It is a double-blind, randomised controlled trial. Twenty-four adult patients who underwent VATS via the uniportal technique were randomised into two groups: the SPSIPB group (n = 12) received SPSIPB along with intravenous patient-controlled analgesia (PCA) with tramadol, whereas the control group (n = 12) received only PCA with tramadol. At the end of the surgery, patients in the SPSIPB group received a unilateral SPSIPB under ultrasound guidance with the use of 30-mL bupivacaine 0.25%. The primary outcome was the numerical rating scale (NRS) scores of the patients. Secondary outcomes included the amount of tramadol and rescue analgesic (paracetamol) consumed by the patients, followed up for post-operative 24 hours. Categorical variables were compared using the Chi-Square Test. Mann-Whitney U Test was used to compare groups of variables that were not normally distributed.
UNASSIGNED: The SPSIPB group had lower NRS values during post-operative 24 hours (P < 0.001). Mean (standard deviation) total tramadol consumption was 58.33 (26.23) mg in the SPSIPB group and 144.17 (13.11) mg in the control group (P < 0.001). Rescue analgesic need was lower in the SPSIP group in the first 18 post-operative hours (P < 0.05).
UNASSIGNED: Serratus posterior superior intercostal plane block provides good analgesia in the thoracic region after video-assisted thoracoscopic surgery.

UNASSIGNED: Thoracolumbar spine surgery is one of the most painful surgical procedures. This study\'s primary objective was to evaluate the effect of erector spinae plane (ESP) block on post-operative cumulative morphine consumption at 24 h in patients undergoing thoracolumbar spine surgery.
UNASSIGNED: Seventy adults posted for thoracolumbar spine surgery were randomised into the control group [Number of patients (n)=35], who received general anaesthesia without any nerve block, and the intervention group (n = 35), who received bilateral ultrasound (US)-guided ESP block at the level of spine surgery with 0.25% bupivacaine 20 mL after standard general anaesthesia. Along with intravenous patient-controlled analgesia morphine, post-operative analgesia was standardised for both groups. Total morphine consumption, visual analogue scale (VAS) score to evaluate pain, overall patient satisfaction, and any side effects were compared at 24 h. The statistical analysis was done using Statistical Package for Social Sciences (SPSS Inc., Chicago, IL).
UNASSIGNED: Post-operative total morphine consumption at 24 h was significantly decreased in the intervention group compared to the control group [5.69 (1.549) versus 9.51 (1.634) mg; P < 0.001]. Post-operative VAS scores were also significantly decreased in the intervention group at rest (P < 0.001) and on movement (P < 0.001). Patient satisfaction scores were more favourable in the intervention group [3.8 (0.4) versus 3.2 (0.6); P < 0.001]. Post-operative nausea and vomiting were found more in the control group but were not significant (n = 14 versus 8; P = 0.127).
UNASSIGNED: US-guided ESP block significantly reduces post-operative morphine consumption and improves analgesia and patient satisfaction without adverse effects in patients undergoing thoracolumbar spine surgery.

UNASSIGNED: Postoperative analgesia is an essential component of enhanced recovery after surgery following abdominal surgery. Studies comparing the effectiveness of epidural analgesia with that of other analgesic modalities after liver surgery have reported inconsistent results. Consequently, the use of epidural analgesia for open hepatectomy is controversial.
UNASSIGNED: The present single-center retrospective study aimed to compare the efficacy and safety of patient-controlled epidural analgesia (PCEA) and patient-controlled intravenous analgesia (PCIA) in adults undergoing open hepatectomy.
UNASSIGNED: Patients who underwent open hepatectomy between January 2018 to December 2019 at Zhongshan Hospital, Fudan University were retrospectively analyzed. Propensity score matching was used to adjust baseline information between the PCEA and PCIA groups. The primary outcome measure was scores of the numeric rating scales (NRSs) for resting, exercise, and nocturnal pain at postoperative 24 h (postoperative day 1 [POD1]) and 48 h (POD2). The secondary outcome indicators included postoperative nausea and vomiting (PONV), hypotension, pruritus, respiratory depression, functional activity score (FAS), effective analgesic pump compression ratio, analgesic relief rate, discontinuation of the analgesic pump, reasons for discontinuation of the analgesic pump, and patient satisfaction with postoperative analgesia.
UNASSIGNED: The NRS scores of the PCEA group on POD1 were significantly lower than those of the PCIA group (P < 0.05). On POD2, the difference between the two groups was significant only for motion NRS scores (P < 0.05). The PCIA group had significantly more patients with lower FAS functional class than the PCEA group (P < 0.001). The effective analgesic pump compression ratio and the analgesic relief rate at 2 days after the surgery were lower in the PCEA group than in the PCIA group (P < 0.001). The incidence of pump discontinuation was higher in the PCEA group than in the PCIA group on POD2 (P = 0.044). Moreover, on POD1 and POD2, the PCEA group showed a higher incidence of pruritus and hypotension than the PCIA group (P < 0.001). Both groups showed no significant difference in PONV incidence.
UNASSIGNED: In patients undergoing open hepatectomy, PCEA was more effective than PCIA in relieving moderate to severe pain on POD1. However, improving the safety and effectiveness of PCEA remains a challenge.
