Radical prostatectomy using the Hinotori robot-assisted surgical system: Docking-free design may contribute to reduction in postoperative pain.

BACKGROUND: The docking-free design of the Japanese Hinotori surgical robotic system allows the robotic arm to avoid trocar grasping, thereby minimising excessive abdominal wall stress. The aim of this study was to evaluate the safety and efficacy of robotic-assisted radical prostatectomy (RARP) using the Hinotori system and to explore the potential contribution of its docking-free design to postoperative pain reduction. METHODS: This study reviewed the clinical records of 94 patients who underwent RARP: 48 patients in the Hinotori group and 46 in the da Vinci Xi group. RESULTS: Hinotori group had significantly longer operative and console times (p = 0.030 and p = 0.029, respectively). Perioperative complications and oncologic outcomes did not differ between the two groups. On postoperative day 4, the rate of decline from the maximum visual analogue scale score was marginally significant in the Hinotori group (p = 0.062). CONCLUSIONS: The docking-free design may contribute to reducing postoperative pain.

Application of Hip Pericapsular Nerve Block Combined With Spinal Anesthesia in the Treatment of Elderly Patients With Femoral Intertrochanteric Fracture.

OBJECTIVE: To investigate the effect of pericapsular nerve group (PENG) block combined with spinal anesthesia in the treatment of elderly patients with intertrochanteric fractures through "rapid diagnosis and treatment channel" PFNA internal fixation. METHODS: 52 elderly patients were randomly divided into the observation group (26 patients, PENG block combined with spinal anesthesia) and the control group (26 patients, spinal anesthesia alone). The general health, mean arterial pressure (MAP), and heart rate (HR) of both groups were compared at various stages: immediately before the administration of pain analgesia, during the positioning of spinal epidural anesthesia, at the beginning and end of the surgery, and 2 hours after surgery. Additionally, VAS scores at rest and during passive straight leg elevation by 15° were evaluated at 12 hours, 24 hours, 48 hours, 72 hours, and 7 days after surgery. RESULTS: The MAP and HR in the observation group under spinal anesthesia in the lateral position were lower than those in the control group (P < 0.05). Additionally, the VAS scores of the observation group during positioning and at 12 hours and 24 hours after surgery were lower than those in the control group under spinal epidural anesthesia (both P < 0.05). CONCLUSION: The application of ultrasound-guided PENG block combined with lumbar anesthesia can reduce pain when in lateral position, stabilize perioperative vital signs, and result in high satisfaction.

Effect of Dexmedetomidine Addition in Erector Spinae Plane Block on Opioid Consumption after Lumbar Spine Surgery.

OBJECTIVE: To investigate the efficacy of adding 0.5 micrograms/kg of dexmedetomidine to 0.2% ropivacaine in erector spinae plane block in terms of 24-hour opioid consumption after lumbar spine surgeries. STUDY DESIGN: A randomised controlled trial. Place and Duration of the Study: The Security Forces Hospital, Riyadh, Saudi Arabia, from 30th November 2022 to 30th March 2023. METHODOLOGY: Patients aged between 18-70 years, ASA 1-3 who were booked to undergo lumbar spine surgeries under general anaesthesia were inducted. Patients in the intervention group received erector spinae plane block (ESPB). Exclusion criteria were patient refusal, inability to give consent, patients with contraindications to regional anaesthesia, known allergy to study medications, inability to use patient-controlled analgesia (PCA), psychiatric disorders or patients using any psychiatric medications. The primary outcome measure of the study was 24-hour opioid consumption. RESULTS: The numeric rating scale (NRS) pain scores were significantly decreased in the ESPB-D group at 30 minutes (p = 0.042), at 1 hour (p = 0.018), at 2 hours (p = 0.044), at 12 hours (p = 0.039), at 18 hours (p = 0.011), and at 24 hours (p = 0.020). Intraoperative use of remifentanil was also significantly lower in the ESPB-D group (p <0.01). ESPB using dexmedetomidine also reduced opioid consumption over a period of 24 hours (p <0.01). Median patient satisfaction score and median ease of mobility were also significantly better in the ESPB-D group. CONCLUSION: Addition of dexmedetomidine in erector spinae plane block reduced pain scores and intraoperative and postoperative opioid consumption after lumbar spine surgery. KEY WORDS: Dexmedetomidine, Erector spinae plane block, Lumbar spine surgery, Opioid consumption, Pain control.

Quality Improvement in an Anaesthesiology and Intensive Care Unit Through Pain Assessment and Control.

The aim of the study is to determine whether the assessment of postoperative pain and timely measures to control it improve the quality of medical care in intensive care units (ICUs). To develop an improvement model with a focus on pain assessment and control. 151 patients were included in the study, divided into two groups: a retrospective group (RG)-60 patients and a prospective group (PG)-91 patients. A multimodal approach to pain control was applied to all patients. We administered the Critical Care Pain Observational Tool (CPOT) to PG upon admission to the ICU. Visual analog scale (VAS) for pain assessment was used in all non intubated patients in 6 hours intervals. In the PG, а model for improvement was applied using a PDSA (Plan, Do, Study/ Check, Act) cycle. The following indicators have been used: process, outcome, and balancing indicators. A survey of the PG was also conducted. The developed Model of improvement increased the VAS score reporting success rate from 40 to 95%, which allowed significantly better pain control. In PG the registered CPOT score was 1.71 ± 0.73. 90% of patients in PG have an average VAS score below 5 after the improvement model, while in RG-50% of patients, which is statistically significant (P < 0.001). There was no statistically significant difference in balancing indicators between the two groups. Conclusion: The conducted survey confirmed the positive effect of the model. Quality improvement in the ICU depends on accurate assessment of postoperative pain and timely and adequate treatment.

The Medipol Combination: Novel Rectointercostal Fascial Plane Block and Pectointercostal Fascial Plane Block for Postoperative Analgesia Management After Cardiac Surgery: A Report of 15 Cases.

The parasternal blocks cannot cover the T7 and lower anterior and lateral branches of the thoracoabdominal nerves. In the open heart surgeries, chest drainage tubes are generally outside the target of the parasternal blocks. Recently, Tulgar et al described a novel interfascial plane block technique named "recto-intercostal fascial plane block" (RIFPB). RIFPB is performed between the rectus abdominis muscle and the sixth to seventh costal cartilages. RIFPB targets the anterior and lateral cutaneous branches of the T6-T9 thoracoabdominal nerves. In this clinical report, we want to share our experiences about pectointercostal plane block and RIFPB combination (Medipol Combination) after cardiac surgery.

Patient-reported pain, satisfaction, adverse effects, and deviations from ambulatory surgery pain medication.

OBJECTIVES: Addressing the challenges of ambulatory surgery involves balancing effective pain relief with minimizing the side effects of pain medication. Due to the heightened risk of opioid abuse, Helsinki University Hospital (Finland) has had a stringent oxycodone prescription policy. This policy prompts an exploration into whether ambulatory surgery patients experience severe post-surgical pain and whether an increase in prescribed opioids would cause elevation in adverse effects. METHODS: This prospective cohort study, with a 1-week follow-up, included 111 adult ambulatory surgery patients (orthopaedics, urology). The patients documented their pain levels within the first postoperative week (using a numerical rating scale [NRS] of 0-10) and pain medication intake up to two days postoperatively. Furthermore, they completed a questionnaire assessing their satisfaction with pain relief, medication-related adverse effects, and adherence to instructions. Medication intake was cross-referenced with the provided instructions and prescriptions. RESULTS: A notable 56% of patients reported experiencing intense pain (NRS ≥5) within a week following surgery. Of these, 52% received a single dose of slow-release oxycodone (5-20 mg) at discharge for use on the night of surgery. Predominantly prescribed pain medications included a combination of paracetamol and codeine (64%) or ibuprofen (62%). Satisfaction rates were high, with 87% expressing satisfaction with pain medication given at hospital discharge and 90% expressing contentment with the prescribed medication. The most common adverse effects were tiredness/grogginess (45%), sleep disturbances (38%), nausea (37%), and constipation (27%). Also, 24% of patients self-reported deviations from medication instructions. A comparison of self-reported and instructed medications revealed that 14% exceeded prescribed dosages, and 28% opted for preparations different from those prescribed. Notably, patients who self-reported deviations from instructions differed from those objectively deviating from instructions. CONCLUSIONS: Although 56% of patients had intense pain, the majority expressed satisfaction with the provided pain relief. Instances of non-adherence to medication instructions were prevalent, often going unnoticed by the patients themselves.

Single-port versus traditional three-port laparoscopic total extraperitoneal inguinal hernia repair: A single-centre, prospective, randomised study.

OBJECTIVE: To explore the efficacy and safety of single-incision laparoscopic (SIL) technique compared with the traditional three-port total extraperitoneal (TEP) technique for inguinal hernia repair. METHODS: This prospective, randomised study involved patients who underwent surgery for inguinal hernia at our hospital from December 2021 to July 2023. Patients were randomly assigned to SIL-TEP or TEP groups based on a computer-generated random number table. Perioperative clinical indicators for the surgical approaches were evaluated. RESULTS: Of the 127 patients eligible for study, 66 were randomised to the SIL-TEP group and 61 to the TEP group. The operation time for SIL-TEP was significantly longer than for TEP but the time to return to normal activities was significantly shorter and short-term pain score was significantly lower. There were no differences between groups in intraoperative blood loss, postoperative hospital stays, pain relief time, hospitalization costs or cosmetic satisfaction scores. CONCLUSION: While SIL-TEP is more challenging than TEP for hernia repair, we found that at our centre it is comparable with regard to overall safety and feasibility. Further studies are needed to validate our findings.

Erector spinae plane block versus paravertebral block on postoperative quality of recovery in obese patients undergoing laparoscopic sleeve gastrectomy: a randomized controlled trial.

Purpose: To compare the impact of erector spinae plane block (ESPB) and paravertebral block (PVB) on the quality of postoperative recovery (QoR) of patients following laparoscopic sleeve gastrectomy (LSG). Methods: A total of 110 patients who underwent elective LSG under general anesthesia were randomly assigned to receive either ultrasound-guided bilateral ESPB or PVB at T8 levels. Before anesthesia induction, 40 mL of 0.33% ropivacaine was administered. The primary outcome was the QoR-15 score at 24 hours postoperatively. Results: At 24 hours postoperatively, the QoR-15 score was comparable between the ESPB and PVB groups (131 (112-140) vs. 124 (111-142.5), P = 0.525). Consistently, there was no significant difference in QoR-15 scores at 48 hours postoperatively, numerical rating scale (NRS) pain scores at any postoperative time points, time to first ambulation, time to first anal exhaust, postoperative cumulative oxycodone consumption, and incidence of postoperative nausea and vomiting (PONV) between the two groups (all P > 0.05). No nerve block-related complications were observed in either group. Conclusion: In patients undergoing LSG, preoperative bilateral ultrasound-guided ESPB yields comparable postoperative recovery to preoperative bilateral ultrasound-guided PVB.

Effect of Oxycodone-Based Multimodal Analgesia on Visceral Pain After Major Laparoscopic Gastrointestinal Surgery: A Randomised, Double-Blind, Controlled Trial.

Purpose: 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. Methods: 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. Results: 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. Conclusion: For patients undergoing major laparoscopic gastrointestinal surgery, oxycodone-based multimodal analgesia reduced postoperative visceral pain in a statistically significant but not clinically important manner. Trial Registration: Chinese Clinical Trial Registry (ChiCTR2100052085).

Outcomes from Early Experience with Laparoscopic Inguinal Hernia Repair Versus Open Technique: Navigating the learning curve.

Objectives: This study aimed to evaluate the outcomes of laparoscopic inguinal hernia repair (LIHR) regarding postoperative pain, recurrence rates, duration of hospital stay and other postoperative outcomes within the context of a tertiary care teaching hospital in South India, and the initial experience of laparoscopic repairs. The current consensus in the literature often suggests LIHR as superior to open inguinal hernia repair (OIHR). Methods: This single-centre, retrospective, observational study was conducted at the Jawaharlal Institute of Postgraduate Education and Research, Puducherry, India, from January 2011 to September 2020. All patients who underwent elective OIHR and LIHR were included. Data on the patients demographics, comorbidities, hernia type, mesh characteristics, surgery duration, hospital stay and immediate postoperative complications were collected and analysed. Results: A total of 2,690 OIHR and 158 LIHR cases were identified. The demographic profiles, hospital stay and complication rates were similar in both groups. However, surgical site infection was present exclusively in the OIHR group (3.55% versus 0.0%; P <0.05). The timeline for returning to normal activities was statistically shorter for the LIHR group (6 versus 8 days; P <0.05). The most frequent immediate complication in the LIHR group was subcutaneous emphysema (6.54% versus 0.0%; P <0.05). Recurrence (9.23% versus 3.61%; P = 0.09) and chronic pain (41.53% versus 13.55%; P <0.05) were higher in the LIHR group. Conclusion: Lower recurrence and chronic pain rates were observed with OIHR in the initial experience with LIHR in the hospital. However, LIHR had significant advantages concerning faster patient recovery and lower rates of surgical site infections. While the results contribute an interesting deviation from the standard narrative, they should be interpreted within the context of a learning curve associated with the early experience of the research team with LIHR.

Opioid-free anaesthesia with dexmedetomidine and lidocaine versus remifentanil-based anaesthesia in cardiac surgery: study protocol of a French randomised, multicentre and single-blinded OFACS trial.

INTRODUCTION: Intraoperative opioids have been used for decades to reduce negative responses to nociception. However, opioids may have several, and sometimes serious, adverse effects. Cardiac surgery exposes patients to a high risk of postoperative complications, some of which are common to those caused by opioids: acute respiratory failure, postoperative cognitive dysfunction, postoperative ileus (POI) or death. An opioid-free anaesthesia (OFA) strategy, based on the use of dexmedetomidine and lidocaine, may limit these adverse effects, but no randomised trials on this issue have been published in cardiac surgery.We hypothesised that OFA versus opioid-based anaesthesia (OBA) may reduce the incidence of major opioid-related complications after cardiac surgery. METHODS AND ANALYSIS: Multicentre, randomised, parallel and single-blinded clinical trial in four cardiac surgical centres in France, including 268 patients scheduled for coronary artery bypass grafting under cardiac bypass, with or without aortic valve replacement. Patients will be randomised to either a control OBA protocol using remifentanil or an OFA protocol using dexmedetomidine/lidocaine. The primary composite endpoint is the occurrence of at least one of the following: (1) postoperative cognitive disorder evaluated by the Confusion Assessment Method for the Intensive Care Unit test, (2) POI, (3) acute respiratory distress or (4) death within the first 48 postoperative hours. Secondary endpoints are postoperative pain, morphine consumption, nausea-vomiting, shock, acute kidney injury, atrioventricular block, pneumonia and length of hospital stay. ETHICS AND DISSEMINATION: This trial has been approved by an independent ethics committee (Comité de Protection des Personnes Ouest III-Angers on 23 February 2021). Results will be submitted in international journals for peer reviewing. TRIAL REGISTRATION NUMBER: NCT04940689, EudraCT 2020-002126-90.

The analgesic effect of ultrasound-guided cervical erector spinae block in arthroscopic shoulder surgery: a randomized controlled clinical trial.

BACKGROUND: Erector spinae plane block (ESPB) is a novel fascial plane block technique that can provide effective perioperative analgesia for thoracic, abdominal and lumbar surgeries. However, the effect of cervical ESPB on postoperative analgesia after arthroscopic shoulder surgery is unknown. The aim of this study is to investigate the analgesic effect and safety of ultrasound-guided cervical ESPB in arthroscopic shoulder surgery. METHODS: Seventy patients undergoing arthroscopy shoulder surgery were randomly assigned to one of two groups: ESPB group (n = 35) or control group (n = 35). Patients in the ESPB group received an ultrasound-guided ESPB at the C7 level with 30 mL of 0.25% ropivacaine 30 min before induction of general anesthesia, whereas patients in the control group received no block. The primary outcome measures were the static visual analogue scale (VAS) pain scores at 4, 12, and 24 h after surgery. Secondary outcomes included heart rate (HR) and mean arterial pressure (MAP) before anesthesia (t1), 5 min after anesthesia (t2), 10 min after skin incision (t3), and 10 min after extubation (t4); intraoperative remifentanil consumption; the Bruggrmann comfort scale (BCS) score, quality of recovery-15 (QoR-15) scale score and the number of patients who required rescue analgesia 24 h after surgery; and adverse events. RESULTS: The static VAS scores at 4, 12 and 24 h after surgery were significantly lower in the ESPB group than those in the control group (2.17 ± 0.71 vs. 3.14 ± 1.19, 1.77 ± 0.77 vs. 2.63 ± 0.84, 0.74 ± 0.66 vs. 1.14 ± 0.88, all P < 0.05). There were no significant differences in HR or MAP at any time point during the perioperative period between the two groups (all P > 0.05). The intraoperative consumption of remifentanil was significantly less in the ESPB group compared to the control group (P < 0.05). The scores of BCS and QoR-15 scale were higher in the ESPB group 24 h after surgery than those in the control group (P < 0.05). Compared to the control group, fewer patients in the ESPB group required rescue analgesia 24 h after surgery (P < 0.05). No serious complications occurred in either group. CONCLUSIONS: Ultrasound-guided cervical ESPB can provide effective postoperative analgesia following arthroscopic shoulder surgery, resulting in a better postoperative recovery with fewer complications.

The persistent benefits of decreasing default pill counts for postoperative narcotic prescriptions.

BACKGROUND: In 2017, a university-based academic healthcare system changed the opioid default pill count from 30 to 12 pills. Modifying the electronic default pill count influences short-term clinician prescribing practices. We sought to understand the long-term impact on postoperative opioid prescribing habits after an opioid default pill count reduction. MATERIALS AND METHODS: A retrospective electronic medical record system (EMRS) review was conducted in a healthcare system comprised of seven affiliated hospitals. Patients who underwent a surgical procedure and were prescribed an opioid on discharge between 2017-2021 were evaluated. All prescriptions were converted into morphine equivalents (MME). Analyses were performed with the chi-square test and Bonferonni adjusted t-test. RESULTS: 191,379 surgical procedures were studied. The average quantity of opioids prescribed decreased from 32 oxycodone 5 mg tablets in 2017 to 21 oxycodone 5 mg tablets in 2021 (236 MME to 154 MME, p<0.001). The percentage of patients obtaining a refill within 90 days of surgery varied between 18.3% and 19.9% (p<0.001). Patients with a pre-existing opioid prescription and opioid-naïve patients both had significant reductions in prescription quantities above the default MME (79.7% to 60.6% vs. 65.3% to 36.9%, p<0.001). There was no significant change in refills for both groups (pre-existing 36.7% to 38.3% (p = 0.1) vs naïve 15.0% to 15.3% (p = 0.29)). CONCLUSIONS: The benefits of decreasing the default opioid pill count continue to accumulate long after the original change. Physician uptake of small changes to default EMRS practices represents a sustainable and effective intervention to reduce the quantities of postoperative opioids prescribed without deleterious effects on outpatient opiate requirements.

Role of scalp nerve block in improving the quality of rehabilitation in patients after meningioma resection: A randomized controlled clinical trial.

BACKGROUND: In this study, we analyzed whether scalp nerve block with ropivacaine can improve the quality of rehabilitation in patients after meningioma resection. METHODS: We included 150 patients who were undergoing craniotomy in our hospital and categorized them into 2 groups - observation group (patients received an additional regional scalp nerve block anesthesia) and control group (patients underwent intravenous general anesthesia for surgery), using the random number table method approach (75 patients in each group). The main indicator of the study was the Karnofsky Performance Scale scores of patients at 3 days postoperatively, and the secondary indicator was the anesthesia satisfaction scores of patients after awakening from anesthesia. The application value of different anesthesia modes was studied and compared in the 2 groups. RESULTS: Patients in the observation group showed better anesthesia effects than those in the control group, with significantly higher Karnofsky Performance Scale scores at 3 days postoperatively (75.02 vs 66.43, P < .05) and anesthesia satisfaction scores. Compared with patients in the control group, patients in the observation group had lower pain degrees at different times after the surgery, markedly lower dose of propofol and remifentanil for anesthesia, and lower incidence of adverse reactions and postoperative complications. In addition, the satisfaction score of the patients and their families for the treatment was higher and the results of all the indicators were better in the observation group than in the control group, with statistically significant differences (P < .05). CONCLUSION: Scalp nerve block with ropivacaine significantly improves the quality of short-term postoperative rehabilitation in patients undergoing elective craniotomy for meningioma resection. This is presumably related to the improvements in intraoperative hemodynamics, relief from postoperative pain, and reduction in postoperative nausea and vomiting.
