Efficacy of different administration methods for labor analgesia / 中国基层医药

Objective:To investigate the clinical efficacy of different administration methods for labor analgesia.Methods:This randomized controlled study was conducted on 152 parturient women who underwent vaginal delivery at the Xinxiang Central Hospital from February to June 2023. These women were divided into a control group and an observation group, with 76 women per group. Women in the control group received 3 mL of 0.1% ropivacaine hydrochloride after routine epidural catheterization, followed by 3 mL of analgesic drugs after 3 minutes. For those without any special reactions, an analgesic pump containing 9 mL of medication was used after 3 minutes until the end of labor. In the observation group, 3 mL of 0.1% ropivacaine hydrochloride was administered as a trial dose before the epidural catheter was inserted into the epidural space. After 3 minutes, the postpartum woman lay flat and was given another 3 mL of analgesic pump medication. After 3 additional minutes, an additional 9 mL of the medication was administered. The analgesic pump was connected and turned on until the catheter was removed after delivery. The epidural catheter failure rate was assessed in each group. Before epidural puncture (T 1), within 30 minutes after the onset of anesthesia (T 2), and at the time of full dilation of the cervix (T 3), Visual Analogue Scale scores, the number of patient attempts to additionally use an analgesia pump, maternal satisfaction, the number of cases requiring cesarean section conversion, the incidence of adverse reactions (such as nausea, vomiting, and fever), and Apgar scores for newborns were recorded in each group. Results:The epidural catheter failure rate in the observation group was 1.3% (1/76), which was significantly lower than 10.5% (8/76) in the control group ( χ2 = 5.79, P < 0.05). At T 2 and T 3, the Visual Analogue Scale score in the observation group was (0.89 ± 0.08) points and (2.1 ± 0.07) points, respectively, which were significantly lower than (2.55 ± 0.07) points and (3.35 ± 0.07) points in the control group ( t = 238.54, 133.17, both P < 0.001). The number of patient attempts to additionally use an analgesia pump in the observation group was (1.00 ± 0.84) counts, which was significantly less than (4.00 ± 0.65) counts in the control group ( t = 29.47, P < 0.001). Maternal satisfaction in the observation group was 100% (76/76), which was significantly higher than 92.1% (70/76) in the control group ( χ2 = 6.25, P < 0.05). The number of cases requiring cesarean section conversion in the observation group was 0 (0/76), which was significantly lower than 52.6% (4/76) in the control group ( χ2 = 4.10, P < 0.05). Conclusion:Administering a trial dose (3 mL) of 0.1% ropivacaine hydrochloride before placing the epidural catheter during labor analgesia can greatly increase the placement success rate of the catheter and enhance pain relief effectiveness. This has a certain clinical application value.

Efficacy of dexmedetomidine for foraminal endoscopic surgery / 中国基层医药

Objectives:To investigate the efficacy of dexmedetomidine for foraminal endoscopic surgery.Methods:A total of 75 patients with lumbar disc herniation who received treatment at the First Affiliated Hospital of Anhui Medical University between September 2020 and May 2021 were included in this study. Using a case-control study method, these patients were divided into three groups according to different treatment methods, with 25 patients in each group. The three groups underwent a single-segment unilateral approach for foraminal endoscopic surgery. Group A received simple process infiltration anesthesia, while Group B and Group C received a pump injection of 0.5 μg/kg/h dexmedetomidine for 20 minutes prior to surgery. Group B underwent post-surgical anesthesia adjustments, which involved joint process infiltration anesthesia that was seamlessly integrated with a pump-administered dexmedetomidine infusion at a rate of 0.4 μg/kg/h throughout the surgical procedure. Group C received joint process infiltration anesthesia that was seamlessly integrated with a pump-administered dexmedetomidine infusion at a rate of 0.6 μg/kg/h throughout the surgical procedure. Vital signs, sedation status, sedation score, length of hospital stay, pain score (VAS) immediately after surgery, pain scores at 3 and 6 hours after surgery, and changes in vital signs at different points during surgery were compared among the three groups.Results:There were no significant differences in age, sex, or surgical segment among the three groups (all P > 0.05). The postoperative length of hospital stay in Groups A, B, and C was (5.12 ± 1.15) days, (3.02 ± 0.42) days, and (3.82 ± 0.54) days, respectively ( F = 32.04, P < 0.01). At the beginning of surgery, the sedation scores in Groups A, B, and C were (1.22 ± 0.29) points, (1.28 ± 0.36) points, and (1.46 ± 0.38) points, respectively ( F = 3.28, P < 0.05). At 30 minutes after surgery, the sedation scores in the three groups were (2.12 ± 0.22) points, (2.16 ± 0.24) points, and (2.20 ± 0.24) points, respectively ( F = 3.72, P < 0.01). Immediately after surgery, the Visual Analogue Scale (VAS) scores in the three groups were (3.52 ± 0.33) points, (2.92 ± 0.55) points, and (2.82 ± 0.54) points, respectively ( F = 15.16, P < 0.01). At 3 hours after surgery, the VAS scores in the three groups were (3.64 ± 0.39) points, (2.60 ± 0.58) points, and (2.74 ± 0.54) points ( F = 30.47, P < 0.01). At 6 hours after surgery, the VAS scores in the three groups were (3.78 ± 0.43) points, (2.52 ± 0.47) points, and (2.74 ± 0.52) points, respectively ( F = 49.90, P < 0.01). There were significant differences in VAS score, heart rate, and mean arterial pressure among the three groups during articular process puncture, cannula expansion of the intervertebral foramen, and capture of the perinerve protrusion nucleus pulposus ( F = 34.59, 148.65, 164.08, 5.08, 10.81, 38.06, 43.62, 37.46, and 38.76, all P < 0.05). Conclusion:Preoperative dexmedetomidine can effectively maintain hemodynamic stability, ensure sedation levels, reduce postoperative pain, and accelerate patient recovery after surgery.

Objective:To investigate the efficacy and value of preemptive analgesia in older adult patients undergoing laparoscopic hepatectomy.Methods:A total of 150 older adult patients with liver cancer, who underwent laparoscopic hepatectomy at The 2 nd Affiliated Hospital of Wenzhou Medical University between July 2019 and April 2020, were randomly assigned to two groups: a control group ( n = 75) and an observation group ( n = 75) using the random number table method. The control group received postoperative analgesia with parecoxib sodium, while the observation group received preemptive analgesia with parecoxib sodium. A comparative analysis was conducted between the control and observation groups in terms of the Numerical Rating Scale (NRS) scores at 8, 12, and 24 hours postoperatively, postoperative recovery, length of hospital stay, and overall cost. Results:There were no statistically significant differences in operation time, dosage of Sufentanil 24 hours postoperatively, or the total and effective usage counts of patient-controlled intravenous analgesia with Sufentanil between the control and observation groups (both P > 0.05). However, the NRS scores of the observation group were significantly lower than those of the control group at 8, 12, and 24 hours postoperatively. Specifically, the NRS scores of the observation group were (4.38 ± 1.24) points, (3.41 ± 0.19) points, and (2.90 ± 0.17) points, respectively, while those of the control group were (5.24 ± 1.01) points, (4.65 ± 1.24) points, and (3.32 ± 1.00) points, respectively ( t = 4.66, 8.56, 3.59, all P < 0.001). Patients in the observation group exhibited significantly more frequent off-bed activities [(2.62 ± 1.24) times], a notably longer cumulative duration of off-bed activities [(1.36 ± 0.20) hours], and a significantly shorter duration of first anal exhaust [(13.50 ± 1.27) hours] compared with those in the control group [(1.06 ± 0.12) times, (0.36 ± 0.09) hours, (20.10 ± 2.16) hours, t = -10.84, -39.49, 22.81, all P < 0.001]. Furthermore, the observation group demonstrated a shorter postoperative hospital stay [(8.90 ± 1.34) days], lower hospitalization costs [(55.8 ± 2.1) thousand yuan], and higher patient satisfaction scores [(88.98 ± 5.64) points] compared with the control group [(11.15 ± 1.29) days, (59.4 ± 6.2) thousand yuan, (72.16 ± 3.26) points, t = 10.48, 4.76, -22.36, all P < 0.001]. Conclusion:The implementation of preemptive analgesia intervention among older adult patients undergoing laparoscopic hepatectomy effectively enhances analgesic outcomes, accelerates postoperative recovery, reduces hospitalization duration, and markedly decreases hospitalization costs.

Objective:To investigate the effects of dezocine combined with sufentanil on continuous epidural analgesia after cesarean section.Methods:Eighty-six pregnant women who were scheduled for cesarean section in Guoyang Hospital of Traditional Chinese Medicine from February to December 2021 were included in this randomized controlled study. These women were divided into an observation group and a control group ( n = 43/group). The women in the observation group underwent epidural analgesia with dizocine, sufentanil, and ropivacaine, while those in the control group underwent epidural analgesia with dizocine and ropivacaine. The visual analogue score, Ramsay sedation score, Bruggrmann comfort scale score, and the incidence of adverse reactions were compared between the two groups. Results:At 4, 8, 12, 24 hours after surgery, the visual analogue score (VAS) in the observation group was significantly lower than that in the control group ( t = 2.34, 5.89, 15.36, 16.23, all P < 0.05). At 4, 8, 12, and 24 hours after surgery, Ramsay sedation score in the observation group was significantly higher than that in the control group ( t = -6.31, -7.64, -7.49, -7.41, all P < 0.001). At 4, 8, 12, and 24 hours after surgery, Bruggrmann comfort scale score in the observation group was significantly higher than that in the control group ( t = -7.60, -10.40, -14.53, -13.80, all P < 0.001). There was a significant difference in the number of effective analgesic pump compressions between the observation and control groups [(3.00 ± 1.41) times vs. (7.23 ± 1.31) times, t = 14.42, P < 0.001]. No adverse reactions were observed in the observation group within 24 hours after surgery. Conclusion:Dezocine combined with sufentanil for epidural analgesia can effectively improve the analgesic effects after cesarean section and is highly safe.

Duration of second stage of labor and its association with pregnancy outcome / 中华围产医学杂志

Objective:To analyze the duration of the second stage of labor without epidural anesthesia and its association with pregnancy outcome.Methods:This retrospective study involved 12 789 women who delivered without epidural anesthesia in the First Affiliated Hospital of Kunming Medical University from January 1, 2014 to December 31, 2017. These subjects were divided into primipara group (9 517 cases) and multipara group (3 272 cases). Demographic characteristics, maternal and neonatal outcomes and the duration of the second stage of labor were compared between the two groups using two independent samples t-test, Mann-Whitney U test and Chi-square test (Fisher's exact test). Differences in the maternal and neonatal outcomes were also analyzed among different subgroups in primiparae [length of second stage: <1 h group ( n=6 265), ≥1-2 h group ( n=2 305), ≥2-3 h group ( n=831) and ≥3 h group ( n=116)] and multiparae [length of second stage <1 h group ( n=3 144), ≥1-2 h group ( n=102) and ≥2 h group ( n=26)]. The association between second stage length and pregnancy outcomes was analyzed with Cramer's V. After adjusted for maternal age, gestational weeks at delivery, body mass index before pregnancy, complications during pregnancy and neonatal birth weight, the relationship between the duration of the second stage and adverse outcomes was analyzed by binary logistic regression analysis. Results:The 95 th percentile of the second-stage labor duration was 143 min for primiparae and 52 min for multiparae. The rates of vaginal delivery, forceps delivery, cesarean section in the second stage, episiotomy, third- or fourth-degree perineal laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion, umbilical arterial blood gas pH<7.15 and transferring to neonatal intensive care unit (NICU) were all correlated with the duration of second stage in primiparae (Cramer's V values: 0.22, 0.23, 0.03, 0.22, 0.05, 0.10, 0.03, 0.03, 0.03 and 0.07, respectively, all P<0.05), and so did those of vaginal delivery, forceps delivery, episiotomy, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, transfusion and transferring to NICU in multiparae (Cramer's V values: 0.18, 0.19, 0.28, 0.14, 0.09, 0.13 and 0.06, respectively, all P<0.05). Logistic analysis showed that in primiparae, the duration of second stage >1 h was an independent risk factor for episiotomy, third- or fourth-degree perineum laceration, forceps delivery, postpartum hemorrhage, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 2.080 (1.907-2.268), 1.773 (1.080-2.911), 1.625 (1.420-1.859), 1.365 (1.231- 1.514), 1.305 (1.165-1.462) and 1.246 (1.081-1.436), respectively], while second stage length >2 h was the independent risk factor for episiotomy, forceps delivery, third- or fourth-degree perineum laceration, postpartum hemorrhage, grade Ⅱ postpartum hemorrhage, blood transfusion, admission to NICU and umbilical arterial blood gas pH<7.15 [adjusted OR (95% CI): 4.844 (4.132-5.678), 4.223 (3.571-4.993), 3.289 (1.806-5.989), 1.952 (1.675-2.274), 1.781 (1.057-3.001), 1.654 (1.025-2.668), 1.682 (1.421-1.991) and 1.298 (1.039-1.620), respectively]. In multiparae, the length of second stage >1 h was an independent risk factor for episiotomy, blood transfusion, forceps delivery, postpartum hemorrhage and admission to NICU [adjusted OR (95% CI): 8.796 (5.717-13.534), 7.469 (2.874-19.411), 6.135 (3.217-11.699), 2.697 (1.624-4.477) and 1.814 (1.063-3.097), respectively], while the duration of second stage >2 h was the independent risk factor for episiotomy, third- or fourth-degree perineum laceration, blood transfusion, grade Ⅱ postpartum hemorrhage, forceps delivery and postpartum hemorrhage [adjusted OR (95% CI): 38.868 (14.948-101.063), 28.046 (2.780-282.490), 20.076 (5.384-74.866), 16.327 (3.406-78.274), 14.337 (5.351-38.411) and 9.036 (3.880-21.011), respectively]. Conclusions:The duration of the second stage of labor without epidural anesthesia is between that reported by Friedman and by Zhang. A prolonged second stage of labor may increase the risk of adverse pregnancy outcomes.

Assessment of main complications of regional anesthesia recorded in an acute pain unit in a tertiary care university hospital: a retrospective cohort

Abstract Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

Continuous erector spinae block for postoperative analgesia in a partial colectomy by subcostal incision / Bloqueo continuo de los erectores espinales para la analgesia postoperatoria en una colectomía parcial por incisión subcostal

Abstract: Erector spinae plane block is an ultrasound-guided technique who has seen a growing role as a perioperative analgesic technique due to its safety profile and versatility. We describe a case of an elderly female with a history of ischemic heart disease and atrial fibrillation, who underwent segmental colectomy by left subcostal laparotomy under general anesthesia, for removal of a colon tumor. An erector spinae plane catheter was placed at the T7 level under ultrasound guidance, and then used for postoperative analgesia. Ropivacaine 0.2% (initial bolus + infusion at 8 mL/h) was used through the catheter, together with intravenous paracetamol and metamizol. This analgesic regimen was maintained for 72 hours, with excellent pain control, after which the catheter was removed. The patient's pain remained controlled and rescue analgesia was not required until her discharge at seven days postoperative. Continuous ESP block was an effective technique for postoperative analgesia in this case, allowing excellent pain control with a low risk of complications and avoiding the use of opioids.

Resumen: El bloqueo del plano del músculo erector espinal es una técnica ecoguiada que ha ganado popularidad como técnica analgésica perioperatoria debido a su perfil de seguridad y versatilidad. Se describe el caso de una anciana con cardiopatía isquémica y fibrilación auricular, a la que se le realizó colectomía segmentaria mediante laparotomía subcostal izquierda bajo anestesia general, para la escisión de un tumor de colon. Se colocó un catéter en el plano del músculo erector espinal al nivel T7 bajo guía ultrasónica y luego se utilizó para analgesia postoperatoria (ropivacaína 0.2% bolo + infusión a 8 mL/h) junto con paracetamol intravenoso y metamizol. Este régimen analgésico se mantuvo durante 72 horas, con excelente control del dolor, tras lo cual se retiró el catéter. La paciente permaneció con adecuada analgesia sin opioides de rescate hasta su alta a los siete días del postoperatorio. El bloqueo del plano del erector espinal torácico continuo fue una técnica eficaz para la analgesia postoperatoria en cirugía abdominal abierta, con bajo riesgo de complicaciones y evitando el uso de opioides.

Preventive effects of hydroxyethyl starch combined with methoxyamine on complications of combined spinal and epidural anesthesia in older adult patients and its influence on hemodynamics / 中国基层医药

Objective:To investigate the preventive effects of hydroxyethyl starch and methoxamine on complications of combined spinal and epidural anesthesia in older adult patients and its influence on hemodynamics.Methods:The clinical data of 120 older adult patients who underwent combined spinal and epidural anesthesia in General Hospital of Armed Police and Marine Police between February 2017 and April 2019 were retrospectively analyzed. The included patients were divided into two groups according to the adverse reactions of drugs used to induce anesthesia: control group (methoxamine injection, n = 55) and observation group (methoxamine + hydroxyethyl starch, n = 65). The changes in hemodynamic index, complications and cognitive function were analyzed in each group. Results:Systolic blood pressures measured at 5, 15 and 30 minutes after anesthesia were (127.53 ± 10.63) mmHg, (119.85 ± 10.86) mmHg, (125.45 ± 10.74) mmHg, respectively in the observation group, which were significantly higher than (118.23 ± 11.32) mmHg, (114.34 ± 10.32) mmHg, (119.01 ± 10.34) mmHg in the control group ( t = 3.66, 2.24, 2.63, all P < 0.05). Diastolic blood pressures measured at 5, 15 and 30 minutes after anesthesia were (76.65 ± 9.07) mmHg, (78.43 ± 9.32) mmHg, (80.19 ± 9.43) mmHg, respectively in the observation group, which were significantly higher than (63.30 ± 9.43) mmHg, (65.98 ± 9.26) mmHg, (70.38 ± 9.17) mmHg in the control group ( t = 6.24, 5.78, 4.55, all P < 0.05). Heart rates measured at 5, 15 and 30 minutes after anesthesia were (73.65 ± 7.67) beats/min, (83.27 ± 9.57) beats/min, (84.10 ± 9.67) beats/min respectively in the observation group, which were significantly higher than (69.76 ± 7.82) beats/min, (64.70 ± 9.38) beats/min, (65.80 ± 9.43) beats/min in the control group ( t = 2.17, 8.46, 8.27, all P < 0.05). The incidences of hypotension and bradycardia in the observation group were 3.08% (2/65) and 3.08% (2/65), respectively, which were significantly lower than 25.45% (14/55) and 21.82% (12/55) in the control group ( χ2 = 12.91, 10.15, both P < 0.05). The Mini Mental State Examination scores measured at 1, 6 and 24 hours after surgery were (26.69 ± 2.51) points, (26.74 ± 2.75) points, and (26.99 ± 2.36) points, respectively in the observation group, which were significantly higher than (23.17 ± 2.41) points, (23.43 ± 2.36) points, and (24.18 ± 2.12) points in the control group ( t = 6.17, 5.55, 5.39, all P < 0.05). Conclusion:Hydroxyethyl starch combined with methoxamine for combined spinal and epidural anesthesia in older adult patients can effectively reduce the hemodynamic fluctuations, decrease the incidences of hypotension and bradycardia, and does not produce a remarkable effect on postoperative cognitive function.

Mechanical pain, degree of postoperative pain, and incidence of complications were recorded in each group.Results:At 6, 24 and 48 hours after surgery, peri-wound pain threshold in the observation group was (119.52 ± 20.42) points, (120.19 ± 17.44) points, (120.94 ± 20.73) points, respectively, which were significantly higher than (108.42 ± 15.24) points, (107.63 ± 16.83) points, (108.47 ± 17.82) points in the control group ( t = 0.01, 0.00, 0.01, all P < 0.05). At 24 and 48 hours after surgery, forearm pain threshold in the observation group was (109.93 ± 15.87) points and (110.79 ± 22.85) points, respectively, which were significantly higher than (97.07 ± 16.49) points and (95.63 ± 24.06) points ( t = 3.37, 2.74, both P < 0.05). There was no significant difference in Ramsay Sedation Scale score between the two groups ( P > 0.05). There was no significant difference in the dose of dizosine used within 48 hours after surgery between the two groups ( P > 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group [8.33% (3/36) vs. 27.78% (10/36), χ2 = 4.60, P < 0.05]. Conclusion:Dexmedetomidine combined with dizosine exhibits obvious analgesic efficacy after lumbar internal fixation. The combined therapy can effectively prevent hyperalgesia with a low incidence of comphications.

Effects of oxycodone multimodal analgesia on quality of awakening and hemodynamics in patients undergoing laparoscopic gynaecological surgery / 中国基层医药

Objective:To investigate the effects of oxycodone multimodal analgesia on quality of awakening and hemodynamics in patients undergoing laparoscopic gynaecological surgery.Methods:Ninety patients who underwent laparoscopic ovarian cyst removal in Weihai Central Hospital from September 2018 to March 2019 were included in this study. They were randomly divided into observation and control groups, with 45 patients in each group. Both groups were given intravenous flurbiprofen axetil (1 mg/kg) for preemptive analgesia. Combined intravenous and inhalation anesthesia was used. The depth of anesthesia was monitored. The observation group was intravenously given 0.10 mg/kg oxycodone and the control group was intravenously given 5 μg sufentanil. Quality of awakening, hemodynamic indexes, postoperative pain score, and incidences of nausea and vomiting were compared between the two groups.Results:Cough score in the observation group was significantly lower than that in the control group [(1.1 ± 0.4) points vs. (1.7 ± 0.7) points, t = -4.99, P < 0.05]. Ramsay Sedation Scale score in the observation group was significantly higher than that in the control group [(3.6 ± 1.0) points vs. (2.8 ± 0.8) points, t = 7.44, P < 0.05]. At 0 (T 1) and 5 minutes (T 2) after extubation, systolic blood pressure in the observation group was (117.7 ± 18.2) mmHg and (118.1 ± 16.2) mmHg, respectively, which were significantly lower than (134.2 ± 16.2) mmHg and (134.5 ± 15.2) mmHg in the control group ( t =-4.54, -4.95, both P < 0.05). There were no significant differences in the incidences of nausea and vomiting between the two groups (both P > 0.05). At 6 and 12 hours after surgery, visual analogue scale score in the observation group was (2.5 ± 0.8) points and (1.1 ± 0.5) points, respectively, which were significantly lower than (3.4 ± 0.9) points and (1.9 ± 0.8) points in the control group ( t = 5.01, -5.68, both P < 0.05). Conclusion:Oxycodone multimodal analgesia for laparoscopic gynaecological surgery can improve the quality of awakening, decrease systolic blood pressure, reduce the degree of postoperative pain, and does not increase the incidences of postoperative nausea and vomiting.

Analgesic effect of dexmedetomidine combined with butorphanol in patients subjected to cardiac surgery / 中国基层医药

Objective:To investigate the effect of dexmedetomidine combined with butorphanol on perioperative analgesia in patients subjected to cardiac surgery.Methods:Sixty-three patients who underwent elective cardiac surgery in Weihai Central Hospital from June 2019 to August 2020 were included in this study. They were divided into propofol + sufentanil group ( n = 21), dexmedetomidine + sufentanil group ( n = 23) and dexmedetomidine + butorphanol group ( n = 19) according to different analgesic methods. Postoperative analgesic satisfaction, Visual Analogue Scale score, hemodynamic changes (heart rate, respiratory rate, systolic blood pressure, diastolic blood pressure) and adverse reactions were compared among the three groups. Results:The satisfaction rate of postoperative analgesia in the dexmedetomidine + butorphanol group was 94.7% (18/19), which was significantly higher than 61.9% (13/21) in the propofol + sufentanil group and 60.8% (14/23) in the dexmedetomidine + sufentanil group ( χ2 = 6.16, 6.57, both P < 0.05). At 4, 12, 24 and 48 hours after tracheal extubation, Visual Analogue Scale score in the dexmedetomidine + butorphanol group were significantly lower than that in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). At the time of tracheal extubation and at 5 minutes after tracheal extubation, heart rate, respiratory rate, systolic blood pressure and diastolic blood pressure in the dexmedetomidine+butorphanol group were significantly lower than those in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). The incidence of adverse reactions in the dexmedetomidine + butorphanol group was 10.5% (2/19), which was significantly lower than 23.8% (5/21) in the propofol + sufentanil group and 30.43% (7/23) in the dexmedetomidine + sufentanil group [30.4% (7/23), χ2=21.94, P < 0.001]. Conclusion:Dexmedetomidine combined with butorphanol in cardiac surgery can not only stabilize postoperative blood pressure and heart rate, but also lower the degree of pain and is highly safe.

Anestesia regional guiada por ultrassom em cirurgias plásticas estéticas das mamas / Ultrasound-guided regional anesthesia in cosmetic plastic surgeries of the breasts

RESUMO A cirurgia de aumento primário de mamas ocupa o topo do ranking dos procedimentos estéticos mais realizado entre as mulheres. Na população masculina, outra cirurgia mamária ocupa lugar de destaque: a ginecomastia. A anestesia regional para as cirurgias plásticas faz parte de uma estratégia de analgesia multimodal que pode reduzir custos, diminuir a hospitalização e a dor no período pós-operatório. O objetivo deste trabalho é revisar e comparar as técnicas de anestesia regional guiadas por ultrassom mais utilizadas para analgesia perioperatória nas cirurgias plásticas estéticas das mamas. Foi realizada a revisão de estudos clínicos que investigaram a associação dos bloqueios anestésicos regionais guiados por ultrassom com cirurgias plásticas estéticas das mamas nos últimos 5 anos na base de dados MEDLINE/PubMed. Foram selecionados 14 artigos para revisão. As técnicas de anestesia regional guiada por ultrassom mais frequentemente relatadas foram o bloqueio paravertebral (BPV), os bloqueios interfasciais (PECS 1 e PECS 2), bloqueio do plano do serrátil (BPS) e bloqueio intercostal (BI). O menor consumo de opioides e melhor controle álgico pós-operatório foi associado ao BPV, PECS 1 e PECS 2 e BPS. O BPV apresentou maior incidência de complicações e os PECS 1 e PECS 2 mostraram-se de execução mais fácil. Os bloqueios interfasciais (PECS 1 e PECS 2) se mostraram mais seguros e de fácil execução nas cirurgias plásticas estéticas das mamas do que as outras modalidades de bloqueios. Promovem diminuição do uso de opioides e seus efeitos colaterais, redução no tempo de internação e na recuperação no pós-operatório.

Abstract Primary breast augmentation surgery is one of the most performed cosmetic procedures among women. In the male population, another breast surgery occupies a prominent place: gynecomastia. Regional anesthesia for plastic surgery is part of a multimodal analgesia strategy that can reduce costs, reduce hospitalization, and pain in the postoperative period. The purpose of this article is to review and compare the most used ultrasound-guided regional anesthesia techniques for perioperative analgesia in aesthetic plastic surgery of the breasts. A review of clinical studies that investigated the association of regional anesthesia techniques guided by ultrasound with cosmetic plastic surgery of the breast in the last 5 years was carried out in the MEDLINE/PubMed database. Fourteen articles were selected for review. The most frequently reported techniques of regional anesthesia guided by ultrasound were paravertebral block (PVB), interfascial block (PECS 1 and PECS 2), serratus plane block (SPB), and intercostal block (IB). The lower consumption of opioids and better postoperative pain control were associated with PVB, PECS 1 and PECS 2, and SPB. PVB had a higher incidence of complications and PECS 1 and PECS 2 proved to be easier to perform. Interfascial blocks (PECS 1 and PECS 2) proved to be safer and easier to perform in cosmetic plastic surgery of the breasts than other types of blocks. They decrease the use of opioids and its side effects, reduce the length of hospital stay and recovery in the postoperative period.

Objective:To investigate the postoperative analgesic efficacy of nabuprofen combined with femoral nerve block in older adult patients subjected to knee arthroplasty and its effects on cognitive function and serum S-100β protein level.Methods:Ninety-one older adult patients subjected to knee arthroplasty between March 2018 and March 2020 in Zhoushan Hospital of Traditional Chinese Medicine were included in this study. They were randomly divided into observation ( n = 45) and control ( n = 46) groups. Patients in both groups received femoral nerve block and catheterization. Naborphine and equal amount of 0.9% sodium chloride injection were intravenously administered in the observation and control groups, respectively for postoperative analgesia. Before and after surgery, Mini-Mental State Examination (MMSE) score, S-100β protein level and Visual Analogue Scale score, and adverse reactions were compared between the observation and control groups. Results:Before surgery, there was no significant difference in MMSE score between the two groups ( P > 0.05). At 3 days after surgery, MMSE score in each group was significantly decreased compared with before surgery (both P < 0.05). At 3 days after surgery, MMSE score in the observation group was significantly higher than that in the control group [(25.34 ± 1.31) points vs. (23.67 ± 1.53) points, t = 5.34, P < 0.05]. Before surgery, there was no significant difference in serum S-100β protein level between the two groups ( P > 0.05). At 1 and 3 days after surgery, serum S-100β protein level in each group was significantly increased compared with before surgery (both P < 0.05). At 7 days after surgery, serum S-100β protein level in each group recovered to pre-operative level. At 1 and 3 days after surgery, serum S-100β protein level in the observation group was significantly lower than that in the control group ( t = 10.20, 9.21, both P < 0.05). At 1, 3, 6, 12 and 24 hours after surgery, the Visual Analogue Scale score in the observation group was (1.14 ± 0.22) points, (1.43 ± 0.25) points, (1.87 ± 0.21) points, (3.56 ± 0.20) points, and (2.63 ± 0.23) points respectively, which was significantly lower than that in the control group [(2.53 ± 0.24) points, (2.53 ± 0.24) points, (3.56 ± 0.20) points, (3.98 ± 0.25) points, (4.23 ± 0.21) points, t = 5.10, 8.15, 9.41, 10.18, 11.42, all P < 0.05]. The incidence of adverse reactions in the observation group was significantly lower than that in the control group [13.33% (6/45) vs. 30.43% (14/46), χ2 = 3.88, P = 0.049]. Conclusion:Naborphine combined with femoral nerve block can effectively improve the postoperative cognitive function of older adult patients undergoing knee arthroplasty, provides good postoperative analgesia, and is highly safe.

Application of transverse abdominis plane block in perioperative pain management of patients with abdominal tumors / 肿瘤研究与临床

Pain is one of the important factors leading to stress. Reasonable perioperative pain management is conducive to reducing stress caused by surgery, reducing the occurrence of adverse events caused by pain, accelerating postoperative recovery, shortening hospitalization time and reducing medical costs, which is one of the important contents emphasized by the concept of enhanced recovery after surgery (ERAS). As a kind of regional nerve block, transverse abdominis plane block (TAPB) is widely used in abdominal pain management due to its simple operation, high success rate and reliable analgesic effect, thus playing an important role in the process of ERAS. The article reviews the anatomical basis, clinical application, influencing factors and limitations of TAPB in order to provide references for the optimization of perioperative pain management in patients with abdominal tumors.

Ventajas de la anestesia intravenosa libre de opioides en cirugía ambulatoria oncológica de mama / Advantages of opioid-free intravenous anesthesia over anesthesia in ambulatory breast cancer surgery

RESUMEN Introducción: la anestesia general libre de opioides surge ante la necesidad de evasión del uso de opioides en el transoperatorio y sus efectos indeseados en el posoperatorio. Objetivo: evaluar el comportamiento hemodinámico y la recuperación anestésica en pacientes intervenidas mediante cirugía ambulatoria por cáncer de mama, en las cuales se administró anestesia general total intravenosa libre de opioides o general balanceada. Métodos: se realizó un estudio cuasiexperimental, prospectivo en pacientes a las que se aplicó anestesia general balanceada (n=34) y total intravenosa libre de opioides (n=34) intervenidas quirúrgicamente por cáncer de mama, en el Hospital General Docente "Abel Santamaría Cuadrado", durante el 2018. Resultados: el grupo de anestesia general balanceada mostró mayor variación intraoperatoria de los parámetros evaluados, con diferencias significativas (p=0,019). El tiempo medio de despertar fue menor en el grupo de anestesia total intravenosa (2,10 ± 0,907 min vs 5,35 ± 1,250 min; p<0,01), al igual que el dolor, con diferencia significativa (p<0,05) y el tiempo de recuperación, donde una hora después de la intervención, el 85 % cumplía los criterios de alta anestésica. El retraso en el alta de la unidad de recuperación ocurrió principalmente por el bajo nivel de actividad motora, con mayor incidencia en el grupo de anestesia general balanceada (71 % vs 26 %; p=0,00). Conclusiones: la anestesia total intravenosa libre de opioides fue superior al método general balanceado, pues mostró mayor estabilidad hemodinámica y analgesia, menor incidencia de complicaciones posoperatorias y menor tiempo de estancia en sala de recuperación posanestésica.

ABSTRACT Introduction: opioid-free general anesthesia arises from the need to avoid the use of opioids in the transoperative period and the undesirable effects in the postoperative period. Objective: to assess the hemodynamic behavior and anesthetic recovery in patients who underwent ambulatory surgery for breast cancer and those who were given either opioid-free intravenous general or balanced general anesthesia. Methods: a quasi-experimental, prospective study was carried out on patients who received balanced general anesthesia (n=34) and total opioid-free intravenous anesthesia (n=34), who underwent breast cancer surgery at Abel Santamaria Cuadrado General Teaching Hospital during 2018. Results: the group of balanced general anesthesia showed greater intraoperative variation of the parameters assessed, with significant differences (p=0.019). The mean time of awakening was lower in the intravenous total anesthesia group (2.10 ± 0,907 min vs. 5,35 ± 1,250 min; p<0.01), as was pain, with significant difference (p<0.05) and the recovery time, where one hour after the surgery, 85 % met the criteria for anesthesia discharge. The delay in discharge from the recovery unit occurred mainly because of the low level of motor activity, with a higher incidence in the group of balanced general anesthesia (71% vs. 26 %; p=0.00). Conclusions: intravenous opioid-free total anesthesia was higher to the balanced general approach because it showed greater hemodynamic and analgesic stability, lower incidence of postoperative complications, and shorter time spent in the post-anesthesia recovery room.

Erector spinae plane block in pediatric orthopedic surgery: two case reports / Bloqueio do plano eretor da espinha em cirurgia ortopédica pediátrica: dois relatos de caso

Abstract The erector spinae plane block is a safe and effective regional anesthesia technique, which has earned new indications perioperatively since its description. We introduce two pediatric anesthesia cases in which we performed the erector spinae plane block during intermediate/major orthopedic surgeries. The first patient is a 2 year-old girl submitted to surgical treatment of developmental dysplasia of the hip. The second patient is a 14 year-old boy submitted to surgical treatment of bilateral clubfoot. This last patient is potentially the first published case in which the erector spinae plane block was performed for ankle and foot surgery. Both cases experienced excellent analgesia, avoiding opiate requirement completely.

Resumo O bloqueio do plano eretor da espinha guiado por ultrassonografia é uma técnica segura e eficaz de anestesia regional, que apresenta novas indicações no perioperatório. Apresentamos dois casos de bloqueio do plano eretor da espinha realizados para analgesia de cirurgia ortopédica pediátrica de médio/grande porte. O primeiro: menina de 2 anos submetida a tratamento cirúrgico de displasia do desenvolvimento do quadril. O segundo: menino de 14 anos submetido a correção de pé valgo bilateral. Este último, no melhor do nosso conhecimento, é o primeiro caso de bloqueio do plano eretor da espinha em cirurgia de tornozelo/pé descrito na literatura. Os casos tiveram analgesia pós-operatória adequada, sem necessidade de opioides.
