RESUMO
BACKGROUND: Regional anaesthesia use is growing worldwide, and there is an increasing emphasis on research in regional anaesthesia to improve patient outcomes. However, priorities for future study remain unclear. We therefore conducted an international research prioritisation exercise, setting the agenda for future investigators and funding bodies. METHODS: We invited members of specialist regional anaesthesia societies from six continents to propose research questions that they felt were unanswered. These were consolidated into representative indicative questions, and a literature review was undertaken to determine if any indicative questions were already answered by published work. Unanswered indicative questions entered a three-round modified Delphi process, whereby 29 experts in regional anaesthesia (representing all participating specialist societies) rated each indicative question for inclusion on a final high priority shortlist. If ≥75% of participants rated an indicative question as 'definitely' include in any round, it was accepted. Indicative questions rated as 'definitely' or 'probably' by <50% of participants in any round were excluded. Retained indicative questions were further ranked based on the rating score in the final Delphi round. The final research priorities were ratified by the Delphi expert group. RESULTS: There were 1318 responses from 516 people in the initial survey, from which 71 indicative questions were formed, of which 68 entered the modified Delphi process. Eleven 'highest priority' research questions were short listed, covering themes of pain management; training and assessment; clinical practice and efficacy; technology and equipment. CONCLUSIONS: We prioritised unanswered research questions in regional anaesthesia. These will inform a coordinated global research strategy for regional anaesthesia and direct investigators to address high-priority areas.

Background: Perioperative glycemic control is an important factor in the clinical management of a patient with diabetes mellitus under surgery. Poorly controlled long-term hyperglycemia not only predisposes individuals to systemic complications of diabetes mellitus and cardiovascular morbidity but also increases the risk of anesthesia and weakens the outcome of the surgery. Given the importance of the issue and the limited studies on glucose control using insulin glargine during surgery, we aimed to investigate the effects of glargine on glucose control in patients with diabetes mellitus during vitrectomy surgery. Methods: This randomized, double-blind trial was conducted in two groups of 35 patients with diabetes mellitus under treatment with insulin. In the control group, the patients received regular insulin based on the blood glucose and the sliding scale, and in the intervention group, they received insulin glargine (0.3 unit/kg) before surgery. From the start of the operation up to 3 hours of the surgery blood glucose of the patients was measured every 45 minutes and once 6 hours after the operation, and if needed, the regular insulin was injected. Data were analyzed using SPSS 16. Frequency, percentage, mean, and standard deviation (SD) were used to describe the data. To compare the quantitative variables, the independent t-test or U-Mann-Whitney test was used. For comparison of the qualitative variables, Chi-square test or Fischer's exact test and repeated measure ANOVA was employed. The significance level (P-value) was considered as p<0.05. Results: Use of insulin glargine was associated with significantly lower blood glucose levels compared to regular insulin at 90-minutes (p=0.004), 135 minutes (p=0.001), and 6 hours after the operation (p=0.005). Conclusion: Glycemic control using glargine compared to regular insulin has a better performance with less need for surplus insulin dose administration during surgery.
RESUMO
BACKGROUND: Spinal block is a common procedure for lower limbs surgery. Fentanyl, a synthetic opioid and dexmedetomidine, a selective α2 agonist have been used as adjuvants in spinal anesthesia to prolong intraoperative and postoperative analgesia. The aim of current study is to compare the efficacy of dexmedetomidine and fentanyl added to intrathecal bupivacaine in orthopedic procedures in lower limbs. METHODS: In this randomized clinical trial, 90 patients undergoing elective lower limb surgeries were randomly allocated to three groups. Via intrathecal approach, the patients received 2.5 ml hyperbaric bupivacaine 0.5% plus 5 micrograms dexmedetomidine (BD group), 25 micrograms fentanyl (BF group) or 0.5 ml normal saline (BN group), respectively. Time to reach the complete motor block, the highest sensory level, regression from block, analgesic request and duration of the drug effect, hemodynamic changes and side effects were compared between the groups. RESULTS: There was no significant difference between the groups regrading time to reach complete motor block, but time to reach the highest sensory level was shorter in group BD than group BF (6.28 ± 1.75 vs. 7.17 ± 1.45, p = 0.03). Group BD had significantly lower mean of NRS 6 h after operation (1.90 ± 0.84 vs. 6.16 ± 1.44 vs. 6.30 ± 1.17, p < 0.001) and longer duration to regress to Bromage 0 (331.60 ± 73.96 vs. 185.56 ± 35.87 vs. 147.03 ± 33.05 min, p < 0.001), to analgesic request (496.63 ± 70.19 vs. 296.33 ± 44.83 vs. 221.83 ± 22.26 min, p < 0.001), to regress two sensory levels (149.00 ± 23.17 vs. 88.90 ± 12.85 vs. 69.33 ± 6.67 min, p < 0.001) and to regress to S1 (560.53 ± 81.86 vs. 329.83 ± 44.10 vs. 241.83 ± 22.26 min, p < 0.001). Serial changes in SBP (p = 0.006), DBP (p = 0.03) and HR (p = 0.002) in group BF were significantly higher than the other two groups. The three groups had comparable side effects. CONCLUSIONS: Using dexmedetomidine as an adjuvant to bupivacaine for spinal anesthesia in lower limb surgeries has longer duration of sensory and motor block and longer postoperative analgesia.

Background: Given the importance of patients' pain after laparoscopic surgeries, this study was conducted to compare the effectiveness of intraperitoneal bupivacaine, acetazolamide, and placebo on pain relief after laparoscopic cholecystectomy surgery. Methods: Patients admitted to Rasool Akram hospital with physical status I or II, based on the American Society of Anesthesiologists (ASA) system, who were candidates for laparoscopic cholecystectomy surgery due to gallstones, were included in this study. Patients were divided into 3 groups (each group containing 20 patients) using block randomization with foursome blocks. Group 1 received bupivacaine, group 2 acetazolamide, and group 3 intravenous saline as placebo. After surgery, pain score was assessed by visual analogue scale, and shoulder pain and analgesic doses were also measured. The mentioned parameters were assessed at 1, 4, 8, 12, and 24 hours after surgery. Results: In this study, 60 patients were included in 3 groups. The mean pain recorded (VAS) at 1, 4, and 8 hours after surgery was not significantly different between acetazolamide and bupivacaine groups, but their score was significantly lower than the placebo group (p<0.05). However, the score recorded at 12 and 24 hours after surgery was not significantly different between the 3 groups (p>0.05). Mean of pain reliever (acetaminophen) injected to the patients when needed was not significantly different among the 3 intervention groups (p<0.05). The highest prevalence of shoulder pain (70%) belonged to the placebo group and the lowest (25%) to acetazolamide (p<0.05). Mean heart rate, systolic blood pressure, diastolic blood pressure, and the respiratory rate were not significantly different among intervention groups in 1, 4, 8, 12, and 24 hours after surgery (p>0.05). Conclusion: According to the results, acetazolamide and bupivacaine injection reduced pain in early hours after laparoscopy. However, pain intensity was not different between intervention groups and the control group after 12 hours, so re-prescription seems to be appropriate at this time. Acetazolamide injection significantly reduces shoulder pains after surgery.
RESUMO
BACKGROUND: Cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. The aim of this study was to compare the effects of modified ultrafiltration (MUF) versus conventional ultrafiltration (CUF) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery. MATERIALS AND METHODS: A randomized clinical trial was conducted on 46 pediatric patients undergoing cardiopulmonary bypass throughout their congenital heart surgery. Arteriovenous MUF plus CUF was performed in 23 patients (intervention group) and sole CUF was performed for other 23 patients (control group). In MUF group, arterial cannula was linked to the filter inlet through the arterial line, and for 10 min, 10 ml/kg/min of blood was filtered and returned via cardioplegia line to the right atrium. Different parameters including hemodynamic variables, length of mechanical ventilation, Intensive Care Unit (ICU) stay, and inotrope requirement were compared between the two groups. RESULTS: At immediate post-MUF phase, there was a statistically significant increase in the mean arterial pressure, systolic blood pressure, and diastolic blood pressure (P < 0.05) only in the study group. Furthermore, there was a significant difference in time of mechanical ventilation (P = 0.004) and ICU stay (P = 0.007) between the two groups. Inotropes including milrinone (P = 0.04), epinephrine (P = 0.001), and dobutamine (P = 0.002) were used significantly less frequently for patients in the intervention than the control group. CONCLUSION: Administration of MUF following surgery improves hemodynamic status of patients and also significantly decreases the duration of mechanical ventilation and inotrope requirement within 48 h after surgery.
RESUMO
Background: Postoperative pain is one of the major problems in patients with femoral or hip fracture. Current study investigates the effect of 0.2% and 0.3% bupivacaine in ultrasound-guided fascia iliaca compartment block (FICB) on postoperative pain. Methods: This randomized clinical trial study was conducted in Rasoul Akram Hospital of Iran University of Medical Sciences. Forty-eight patients with femoral or hip fractures who were candidates for surgery underwent FICB, divided into two groups receiving bupivacaine in 0.2% and 0.3% concentrations. Pain was evaluated with Visual Analog Scale (VAS) at times 2, 6, 12, 24, and 48 hours after surgery. Need for opioids, nausea and vomiting after surgery, patients' satisfaction with pain control and motor block were also recorded. T-test or Mann- Whitney U test and Repeated measure ANOVA was used for analysis. Results: Pain score after surgery was significantly lower in groups receiving 0.3% than the group receiving 0.2% concentration. Patients' satisfaction with pain control in 0.2% group was significantly higher (p=0.04). Time to analgesic onset in both groups had no significant differences (p=0.5). The incidence of nausea and vomiting (p=0.5) and opioid consumption (p=0.1) between the two groups showed no significant difference. Conclusion: In femoral or hip fracture, bupivacaine with 0.3% concentration in fascia iliaca compartment block can cause lower pain score compared to bupivacaine with 0.2% concentration, but patients' satisfaction with pain control and severity of motor block is higher in bupivacaine 0.2%.
RESUMO
BACKGROUND: Controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. One of the commonly used drugs for this purpose is remifentanil. Another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. The aim of this study was to compare the effect of dexmedetomidine with remifentanil in spinal operation. METHODS: In a double blind randomized clinical trial, using random sampling method, 60 patients with the age range of 15-65 years who were candidates for posterior spinal fusion operation were included. Induction of anesthesia was performed, and both groups received isoflurane 1% during the surgery. Remifentanil was injected via infusion pump in one group. The patients in the trial group received dexmedetomidine. As trial outcomes, heart rate and blood pressure were measured before, after induction and during the operation. Pain score, sedation score and the need to analgesic therapy were recorded in the recovery room and the ward. Independent sample t-test and chi-square were used for statistical analysis. RESULTS: Dexmedetomidine had a significant lowering impact on intraoperative blood pressure and heart rate compared to remifentanil (p<0.001). The mean of sedation scores after extubation in patients who received dexmedetomidine was significantly higher than the sedation scores in patients who received remifentanil (p<0.001). The mean of post-extubation and recovery pain score in patients taking remifentanil was significantly higher than patients taking dexmedetomidine (p<0.05). CONCLUSION: Dexmedetomidine in patients with spinal operation is associated with lower postoperative pain score and intraoperative bleeding. Hemodynamic effects are significantly better in patients received dexmedetomidine.
RESUMO
BACKGROUND: Opiate is used in patient-controlled intravenous analgesia pumps (PCIA) for controlling pain in post-surgical patients. Other drugs are remarkably added to opioid pumps to enhance quality, lengthen analgesia, and reduce side effects. Lidocaine, a local anesthetic which inhibits sodium channels, has anesthetic and analgesic effects when injected locally or intravenously. The objective of this study is to evaluate the analgesic effects of adding lidocaine 1% to different doses of morphine via IV pump to patient-controlled analgesia (PCA) after orthopedic surgeries. MATERIALS AND METHODS: In a randomized clinical trial, 60 patients who had undergone orthopedic surgery of lower extremities were divided into three equal groups to control postoperative pain. Intravenous pump with 5 ml/h flow rate was used as the analgesic method. The solution consisted of lidocaine 1% plus 20 mg morphine for the first group, lidocaine 1% plus 10 mg morphine for the second group, and only 20 mg morphine for the third group (control group). Patients were checked every 12 h, and Visual Analog Scale (VAS), extra opioid doses, nausea/vomiting, and sedation scale were examined. RESULTS: Pain score was lower in the first group compared to the other two groups. Mean VAS was 2.15 ± 0.2, 2.75 ± 0.2, and 2 ± 0.25 on the first day and 1.88 ± 0.1, 2.74 ± 0.3, and 2.40 ± 0.3 on the second day, respectively, in the three groups and the difference was statistically significant (P < 0.01 and <0.05, respectively). Also, 10% of patients in the first group needed extra opioid doses, while this figure was 30% in the second group and 25% in the third group (P < 0.01). Nausea/vomiting and sedation scores were not statistically different among the three groups. CONCLUSION: Compared to lidocaine 1% plus 10 mg morphine or 20 mg morphine alone in PCIA, adding lidocaine 1% to 20 mg morphine decreases the pain score and opioid dose after orthopedic surgeries without having side effects.
RESUMO
BACKGROUND: Osteoarthritis is one of the most common diseases and the knee is the most commonly affected joint. Intra-articular prolotherapy is being utilized in acute and chronic pain management setting. This study was designed to compare the efficacy of three methods of intra-articular knee joint therapies with erythropoietin, dextrose, and pulsed radiofrequency. MATERIALS AND METHODS: After approval by the Ethics Committee and explaining the therapeutic method to volunteers, 70 patients who were suffering from primary knee osteoarthrosis went through one of the treatment methods (erythropoietin, dextrose, and pulsed radiofrequency). The study was double-blind randomized clinical trial performed from December 2012 to July 2013. Patients' pain level was assessed through the visual analog pain scale (VAS), and range of motion (ROM) was measured by goniometric method. Furthermore, patients' satisfaction was assessed before and after different treatment methods in weeks 2, 4, and 12. For analysis, Chi-square, one-way ANOVA, and repeated measured ANOVA were utilized. RESULTS: The demographic results among the three groups did not indicate any statistical difference. The mean VAS in erythropoietin group in the 2(nd), 4(th), and 12(th) weeks was 3.15 ± 1.08, 3.15 ± 1.08, and 3.5 ± 1.23, respectively (P ≤ 0.005). Knee joint ROM in the erythropoietin group in the 2(nd), 4(th), and 12(th) weeks was 124 ± 1.50, 124 ± 1.4, and 123 ± 1.53 respectively (P ≤ 0.005). Satisfaction score in the 12(th) week in erythropoietin group was extremely satisfied 15%, satisfied 55%, and moderately satisfied 30%, (P = 0.005). No specific side-effects were observed. CONCLUSION: Intra-articular prolotherapy with erythropoietin was more effective in terms of pain level reduction and ROM improvement compared with dextrose and pulsed radiofrequency.
RESUMO
Background: Lumbar spinal stenosis (LSS) is the most common indication for lumbar surgery in elderly patients. Epidural injections of calcitonin are effective in managing LSS. Objectives: This study aimed to compare the efficacy of transforaminal and caudal injections of calcitonin in patients with LSS. Methods: In this double-blind randomized clinical trial, LSS patients were divided into two equal groups (N = 20). The first group received 50 IU (international units) of calcitonin via caudal epidural injection (CEI), and the second group received 50 IU of calcitonin via transforaminal epidural injection (TEI). The Visual Analogue Scale (VAS) and Oswestry Low Back Pain Disability Questionnaire (ODI) were used to assess the patient's pain and ability to stand, respectively. Visual Analogue Scale and ODI scores were recorded and analyzed. Results: The results showed that caudal and TEIs of calcitonin significantly improved pain and ability to stand during follow-up compared to before intervention (P < 0.05). Additionally, CEI of calcitonin after 6 months significantly reduced pain in LSS patients compared to TEI of calcitonin (P < 0.05). However, no significant difference was observed between the two epidural injection techniques in improving the patient's ability to stand (P > 0.05). Conclusions: The results of the study indicate that epidural injection of calcitonin in long-term follow-up (6 months) had a significant effect on improving pain intensity and mobility in patients with LSS, and its effect on pain in the TEI method was significantly greater than that in the CEI method.
RESUMO
BACKGROUND: Elective knee surgery for repairing anterior cruciate ligament is usually associated with moderate to severe postoperative pain, and, therefore, selecting appropriate analgesia can considerably facilitate pain control and patient's discharge. This study was designed to compare the analgesic effectiveness of administration of ropivacaine or ropivacaine plus ketamine on pain control and improvement of muscle weakness after anterior cruciate ligament repair in adults. MATERIALS AND METHODS: A double-blind randomized study which performed in Operating room and Sixty six patients with American Society of Anesthesiologists health status I to II that underwent elective knee surgery for repairing anterior cruciate ligament under spinal anesthesia were enrolled. Patients were randomly allocated to receive either ropivacaine 0.2% or an equivalent volume of ropivacaine 0.1% plus 1.0 mg/kg ketamine via continuous femoral block with pump infusion. The patients were familiarized with a 10-point verbal analog scale. Quadriceps muscle weakness and sedation score were assessed based on relevant scales. Parameters assessment were obtained from all patients immediately after PACU entrance, and postoperative assessment was performed at 4, 8, 12, 16, 20, 24, 30, 36, 42, and 48 h after the operation. RESULTS: The data of 31 patients who received ropivacaine and of 33 patients in ketamine-ropivacaine group were eligible for analysis. Visual analogue scale (VAS) scores differed at various time points after surgery, with higher scores in patients who received concomitant ketamine and ropivacaine (P < 0.05). The degree of quadriceps muscle weakness was similar between the groups at the different time points. Patients in ropivacaine group rated better quality of pain control with appropriate sedation in comparison with the patients in ketamine/ropivacaine group. CONCLUSION: Our study shows that the addition of a ketamine 1 mg/kg to 0.1% ropivacaine via pump infusion after repairing anterior cruciate ligament could not improve pain control and muscle weakness.
RESUMO
Introduction: Electrical storms and ventricular tachycardia are two life-threatening arrhythmias that are becoming more common. In developing ventricular arrhythmias, the sympathetic nervous system plays a vital role. Stellate ganglion (SG) block can be used in many situations as an important therapeutic target, like treating tachyarryhthmias and ventricular tachyarrhythmias. Case Presentation: The patient was a 53 years old woman with a history of implantable cardioverter defibrillator (ICD) insertion due to ventricular tachycardia. The patient complained of an awkward and unpleasant sensation when the ICD sensed the tachyarrhythmia and shocked her. Regarding the positive response to the previous SG block, with the goal of a longer duration of this effect, stellate ganglion radiofrequency was performed. Conclusions: Stellate ganglion radiofrequency shows a safe and long-term effect for patients with tachyarrhythmias and ICD who cannot tolerate episodes of ICD activation.
RESUMO
Background: Continuous epidural infusion (CEI) has been an optimal and acceptable technique for inducing epidural anesthesia. This study compared two methods of programmed intermittent epidural bolus (PIEB) with CEI in labor analgesia among patients receiving epidural dexmedetomidine. Methods: This study was a randomized clinical trial. The target population was term women candidates for epidural anesthesia. After selection of sample size based on inclusion criteria, a total of 3 cc of dexmedetomidine (0.5 µg/ml) and Ropivacaine 0.1% was injected. Furthermore, 5 ml was injected as a loading dose of dexmedetomidine 0.5 µg /ml and Ropivacaine 0.1%. Then the pain score was recorded. SPSS software Version 23 was used for statistical analysis of data. Results: The neonatal Apgar score in PIEB method was more improved (P = 0.003) and the use of assisted delivery tools such as vacuum, in PIEB method was reduced. (p=0.038) Duration of the first phase of the labor in this method was more reduced than CEI.(p=0.015) Patients in the group undergoing epidural anesthesia by PIEB method were associated with a higher level of satisfaction with the delivery process (p < 0.05) than patients undergoing CEI protocol. Conclusion: PIEB method is associated with further improvement in neonatal Apgar score and maternal outcomes (reduction in the duration of the first phase of labor and no need to use assisted delivery methods) compared to the CEI protocol, but has little effect on hemodynamic conditions or drug dosage.
RESUMO
Introduction: The erector spinae plane (ESP) block is a regional anesthetic technique that involves injecting a local anesthetic below the erector spinae muscle in an interfascial plane. Case Presentation: We report a case of a 66-year-old man with cervicothoracic junction pain caused by an advanced Pancoast tumor. The administration of ESP block at the T2-T3 level led to pain relief of more than 50% in this patient after two sessions. Conclusions: Therefore, the application of this method of regional analgesia is both convenient and safe and reduces opioid consumption. Further studies are needed to evaluate the safety and effectiveness of continuous blocks in outpatient settings.
RESUMO
BACKGROUND: Regional anesthesia is widely used to perform different surgical procedures including those performed on the extremities. In this study, the anesthetic effects of adding intrathecal neostigmine or magnesium sulphate to bupivacaine in patients under lower extremities surgeries were assessed. MATERIALS AND METHODS: In this double-blind randomized clinical trial, 90 patients, candidate for lower extremities surgeries in a training hospital, were recruited. The patients with ASA class I and II aging from 20 to 65 years between 2009 and 2010 were evaluated. The selected patients were randomly assigned to receive either bupivacaine alone (Group A, n=30), or bupivacaine plus magnesium sulphate 50% (Group B, n=30), or bupivacaine plus neostigmine (Group C, n=30). Then sensory and motor onset and complete block and the time of recovery were measured. RESULTS: The sensory block onset time were 3.03 ± 0.981 in group A, 3.90 ± 2.71 in group B and 3.7 ± 1.08 in group C and knee flexion time were not significantly different among the three groups (P > 0.05), whereas the time to complete motor block was significantly longer in group C and motor recovery time were significantly different between groups (P=0.001). CONCLUSIONS: According to the obtained results, it may be concluded that magnesium sulphate is a safe and effective adjuvant for increasing the onset time of motor block.
RESUMO
Nowadays, there are various methods to manage pain after laparoscopic cholecystectomy. The aim of this study was to compare the effectof preemptive versus postoperative use of ultrasound-guided transversus abdominis plane (USG-TAP) block on pain relief after laparoscopic cholecystectomy. In this single-blinded randomized clinical trial, the patients who were candidates for laparoscopic cholecystectomy were randomly divided into the two groups (n = 38 per group). In the preemptive group (PG) after the induction of anesthesia and in the postoperative group (POG) after the end of surgery and before the extubation, bilateral ultrasound-guided transversus abdominis plane (TAP) block was performed on patients using 20 cc of ropivacaine 0.25%. Both groups received patient controlled IV analgesia (PCIA) containing Acetaminophen (20 mg/ml) plus ketorolac (0.6 mg/ml) as a standard postoperative analgesia and meperidine 20 mg q 4 h PRN for rescue analgesia. Using the numerical rating scales (NSR), the patients' pain intensity was assessed at time of arrival to the PACU and in 2th, 4th, 8th, 12th, 24th h. Primary outcome of interest is NSR at rest and coughing in the PACU and in 2th, 4th, 8th, 12th, 24th h. Secondary outcomes of interests were the time to first post-surgical rescue analgesic and level of patients' pain control satisfaction in the first 24 h. The USG-TAP block significantly decreased pain score in the POG compared to the PG, and also the pain was relieved at rest especially in 8 and 12 h (p value ≤ 0.05) after the surgery. Pain score after coughing during recovery at 2, 8 and 12 h after the operation were significantly decreased. (p value ≤ 0.05) The patient satisfaction scores in the POG were significantly higher in all times. There was a statistically significant difference between the two groups in terms of rate of postoperative nausea and vomiting (PONV), indicating that patients in the POG had significantly lower incidences of the PONV compared tothe PG. The time to first analgesic request was significantly shorterin the POG, which was statistically significant (p value = 0.089). There was no statistically significant difference between the two groups in terms of consumption of analgesics. The postoperative TAP block could offer better postoperative analgesia than preepmtive TAP block.

Colecistectomia LaparoscópicaRESUMO
Context: This systematic review and meta-analysis evaluated the effect of the intra-articular injection of platelet-rich plasma (PRP) and oxygen-ozone therapy and provided an evidence-based methodology to treat KOA. Method: Databases, including Cochrane Library, PubMed, and EMBASE, were searched. The retrieval period was before 2021. Two reviewers performed the process of screening and data extraction. Mean differences were calculated [95% confidence interval (CI)] with an inverse-variance method and fixed effect model. Meta-analysis was performed using the latest version of STATA version 16. Results: A total of 12 studies out of 769 articles were evaluated. The mean difference of visual analog scale score between ozone and control groups in the first month after injection was -0.02 (MD, -0.02; 95% CI: -0.32, 0.28; P < 0.05). Mean differences of WOMAC pain, stiffness, and physical function score between baseline and after PRP were -3.53 (MD: -3.53; 95% CI: -4.04, -3.02; P = 0.00), -0.60 (MD: -0.60; 95% CI: -4.0 - 0.864, -0.34; P = 0.00), and -5.96 (MD: -5.96; 95% CI: -7.83, -4.09; P = 0.00). Conclusions: Our results showed that to treat knee osteoarthritis, using PRP for a longer period of 6 - 12 months after the intervention shows better clinical results, while oxygen-ozone therapy has short-term results.
RESUMO
Background: Post-laparoscopic cholecystectomy (LC) pain control is still an issue postoperatively. Objectives: We investigated the effectiveness of the unilateral right-side ultrasound-guided erector spinae plane block (ESPB) on post-LC pain intensity and opioid consumption. Methods: This is a parallel-arm randomized control trial on 62 adult patients with an American Society of Anesthesiologists (ASA) physical status ≤ 2 who underwent LC. The patients were randomized into 2 groups (the block group [BG] and the control group [CG]; n = 31 per group). BG received a single-shot right-sided T7 ESPB with 20 mL of 0.2% ropivacaine at arrival time in the post-anesthesia care unit (PACU). CG) received no regional anesthesia. Both groups received patient-controlled intravenous fentanyl and rescue meperidine for analgesia. The primary outcome was the pain intensity determined using a Numerical Rating Scale (NRS) in the first 24 hours after surgery. Secondary outcomes included total fentanyl and meperidine consumption within 24 hours. Results: Median pain scores were significantly higher in CG at rest and with coughing up to 12 hours after surgery compared with BG. Pain scores were higher in CG with a cough at 24 hours compared with BG (median 1 [interquartile range (IQR) 1, 2] vs. 1 [1, 0]; P = 0.0005). Total fentanyl consumption and meperidine consumption within 24 hours were significantly lower in BG compared with CG (median 60 µg [IQR 60, 90] vs 250 µg [90, 300]; P < 0.0001 and median 20 µg [IQR 10, 20] vs 25 [20, 25]; P = 0.002, respectively). Conclusions: A single-shot, right-sided, unilateral ESPB decreases post-LC opioid consumption and pain.
