Background: We aimed to investigate the effect of transforaminal injection of Magnesium sulphate versus Ozone on pain intensity, functional disability and the oxidative stress biomarkers; superoxide dismutase (SOD) and Glutathione (GSH) in patients with lumbar disc prolapse. Methods: This randomized controlled trial was conducted on 135 patients having symptomatic lumbar disc prolapse, received either transforaminal injection of Magnesium sulphate with steroids, Ozone with steroids, or steroids alone. Assessment of pain severity and functional disability were done before intervention, 2 weeks, 1, 3, and 6 months after intervention. Serum SOD and GSH were measured for all included patients before and 2 weeks after intervention. Results: There was a statistically significant improvement in pain intensity and functional disability 2 weeks after intervention in the three groups, but at 1-month and 3-months after intervention, the significant improvement was in Mg sulphate and Ozone groups only. At 6-months follow up, Mg sulphate group only showed a significant improvement. There was a statistically significant increase in SOD and GSH serum levels, 2-weeks after intervention in both Magnesium sulphate (P-value = 0.002, 0.005 respectively) and ozone groups (P-value < 0.001, < 0.001), but there was no statistically significant change in SOD and GSH serum levels in control group. Conclusion: Transforaminal injection of Mg sulphate in patients with lumbar disc prolapse causes significant longterm improvement (up to 6 months) in pain intensity and functional disability. The serum levels of SOD and GSH were significantly increased at 2 weeks following both transforaminal injection of Mg sulphate and ozone....
Background: The majority of patients may experience atelectasis under general anesthesia, and the Trendelenburg position and pneumoperitoneum can aggravate atelectasis during laparoscopic surgery, which promotes postoperative pulmonary complications. Lung recruitment manoeuvres have been proven to reduce perioperative atelectasis, but it remains controversial which method is optimal. Ultrasonic imaging can be conducive to confirming the effect of lung recruitment manoeuvres. The purpose of our study was to assess the effects of ultrasound-guided alveolar recruitment manoeuvres by ultrasonography on reducing perioperative atelectasis and to check whether the effects of recruitment manoeuvres under ultrasound guidance (visual and semiquantitative) on atelectasis are superior to sustained inflation recruitment manoeuvres (classical and widely used) in laparoscopic gynaecological surgery. Methods: In this randomized, controlled, double-blinded study, women undergoing laparoscopic gynecological surgery were enrolled. Patients were randomly assigned to receive either lung ultrasound-guided alveolar recruitment manoeuvres (UD group), sustained inflation alveolar recruitment manoeuvres (SI group), or no RMs (C group) using a computer-generated table of random numbers. Lung ultrasonography was performed at four predefined time points. The primary outcome was the difference in lung ultrasound score (LUS) among groups at the end of surgery. Results: Lung ultrasound scores in the UD group were significantly lower than those in both the SI group and the C group immediately after the end of surgery (7.67 ± 1.15 versus 9.70 ± 102, difference, -2.03 [95% confidence interval, -2.77 to -1.29], P < 0.001; 7.67 ± 1.15 versus 11.73 ± 1.96, difference, -4.07 [95% confidence interval, -4.81 to -3.33], P < 0.001;, respectively). The intergroup differences were sustained until 30 min after tracheal extubation (9.33 ± 0.96 versus 11.13 ± 0.97, difference, -1.80 [95% confidence interval, -2.42 to -1.18], P < 0.001; 9.33 ± 0.96 versus 10.77 ± 1.57, difference, -1.43 [95% confidence interval, -2.05 to -0.82], P < 0.001;, respectively). The SI group had a significantly lower LUS than the C group at the end of surgery (9.70 ± 1.02 versus 11.73 ± 1.96, difference, -2.03 [95% confidence interval, -2.77 to -1.29] P < 0.001), but the benefit did not persist 30 min after tracheal extubation. Conclusions: During general anesthesia, ultrasound-guided recruitment manoeuvres can reduce perioperative aeration loss and improve oxygenation. Furthermore, these effects of ultrasound-guided recruitment manoeuvres on atelectasis are superior to sustained inflation recruitment manoeuvres.

Background: Opioids remain the mainstream therapy for post-surgical pain. The choice of opioids administered by patient-controlled intravenous analgesia (PCIA) for thoracoscopic lung surgery is unclear. This study compared 3 opioid analgesics for achieving satisfactory analgesia with minimal emesis (SAME). Methods: This randomized clinical trial enrolled patients scheduled for thoracoscopic lung surgery randomized to receive 1 of 3 opioids for PCIA: oxycodone (group O), hydromorphone (group H), and sufentanil (group S). The primary outcome was the proportion of subjects achieving SAME, i.e., no-to-mild pain (pain score < 4/10) with minimal nausea/ vomiting (PONV score < 2/4) when coughing during the pulmonary rehabilitation exercise in the first 3 postoperative days. Results: Of 555 enrolled patients, 184 patients in group O, 186 in group H and 184 in group S were included in the final analysis. The primary outcome of SAME was significantly different among group O, H and S (41.3% vs 40.3% vs 29.9%, P = 0.043), but no difference was observed between pairwise group comparisons. Patients in groups O and H had lower pain scores when coughing on the second day after surgery than those in group S, both with mean differences of 1 (3(3,4) and 3(3,4) vs 4(3,4), P = 0.009 and 0.039, respectively). The PONV scores were comparable between three groups (P > 0.05). There were no differences in other opioid-related side effects, patient satisfaction score, and QoR-15 score among three groups. Conclusions: Given clinically relevant benefits detected, PCIA with oxycodone or hydromorphone is superior to sufentanil for achieving SAME as a supplement to multimodal analgesia in patients undergoing thoracoscopic lung surgery.

Background: Remimazolam is a newer benzodiazepine with properties of rapid onset, short duration of action, and fast recovery. Our study was to evaluate the effects of different doses of remimazolam combined with alfentanil in colonoscopic polypectomy. Methods: One hundred twenty patients were randomly divided into four groups: alfentanil and propofol (AP) group, alfentanil and remimazolam 0.1 mg/kg (AR1 group), 0.15 mg/kg (AR2 group), or 0.2 mg/kg (AR3 group). Patients in the four groups received alfentanil 10 μg/kg, followed by propofol 2 mg/kg and three dosages of remimazolam. Modified Observer’s Assessment of Alertness and Sedation (MOAA/S) scale, heart rate (HR), oxygen saturation (SpO2), respiratory rate (RR), bispectral index (BIS) values and mean arterial pressure (MAP) were collected at intervals of 5 min and analyzed at different time points: before anesthesia (T0), 5 min (T1), 10 min (T2), 15 min after anesthesia (T3) and at the end of surgery (T4). The average MAP was calculated utilizing the average of all MAP values. The primary outcome was the success rate of sedation. Secondary outcomes included time to full alert and adverse events. Results: The success rate of sedation was 100% among the four groups. The incidence of hypotension was significantly decreased (all P < 0.05) and the average MAP was higher in AR1-AR3 groups than AP group (all P < 0.001). None of the patients developed bradycardia or hypertension during surgery in all study groups. BIS values were higher (all P < 0.001) and the time to full alert was statistically shorter in AR1-AR3 groups (all P < 0.05) compared with the AP group. The MOAA/S score in AR1 was higher than AR2 (P < 0.05) and the AR3 group (P < 0.05) at T1 and BIS values in the AR1 group were significantly higher than AR3 group (P < 0.05) at T4. Conclusions: Remimazolam combined with alfentanil have a non-inferior sedative effect than propofol during the colonoscopic polypectomy. Moreover, this combination of two short-acting drugs might be a safer alternative. Trial registration: The clinical trial was registered on (16/05/2021, ChiCTR2100046492)....
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 patientreported 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....
