ABSTRACT

Objective:To investigate the analgesic efficacy of dexmedetomidine combined with dizosine after lumbar internal fixation and its effects on hyperalgesia.Methods:Seventy-two patients who underwent lumbar internal fixation in General Hospital of Armed Police and Marine Police between April 2018 and June 2019 were included in this study. They were randomly assigned to undergo either flurbiprofen axetil and dizosine administration (control group) or dexmedetomidine and dizosine (observation group) for postoperative analgesia. 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.

ABSTRACT

Objective:To evaluate the efficacy of erector spinae plane block (ESPB) for transforaminal endoscopic surgery.Methods:Sixty patients of both sexed, aged 20-45 yr, with body mass index of 17.5-29.0 kg/m 2, of American Society of Anesthesiologists physical status ⅠorⅡ, undergoing percutaneous transforaminal endoscopic lumbar discectomy, were divided into 2 groups ( n=30 each) by using a random number table method: ESPB group (E group) and local infiltration anesthesia group (L group). Group E received the ultrasound-guided ESPB, group L received layer-by-layer-assisted local infiltration anesthesia (including subcutaneous layer and fascia, muscular layer and superior articular process) according to the location of operation, and 0.5% ropivacaine 20 ml was used as local anesthetic in both groups.Operation time and C-arm X-ray localization time were recorded.Visual analogue scale score and Ramsay sedation score were recorded at skin incision (T 1), muscle separation (T 2), foraminoplasty (T 3), nerve root decompression (T 4) and skin suture (T 5). The effective analgesia and satisfaction with sedation were recorded.Patients were followed up postoperatively for patient satisfaction, lower extremity motor block, development of nausea and vomiting, dizziness, hematoma at puncture site, nerve damage and etc.Functional status was assessed using the Oswestry Disability Index. Results:Compared with group L, visual analogue scale scores were significantly decreased at T 2-4, Ramsay sedation scores were increased at T 3, 4, patient′s satisfaction was increased, operation time and C-arm X-ray localization time were shortened ( P<0.05), and no significant change was found in Oswestry Disability Index score or rate of satisfactory analgesia in group E ( P>0.05). No motor block, nausea and vomiting, dizziness, hematoma at puncture site and nerve damage was found in both groups. Conclusion:ESPB can provide satisfactory analgesia with a higher safety when used for trasforaminal endoscopic surgery.

ABSTRACT

Objective To investigate the safety and effectiveness of different intravenous anesthesia methods for pediatric ERCP . Methods Data of 45 children undergoing ERCP at the Affiliated Hangzhou Hospital of Nanjing Medical University from August 2013 to July 2016, including intravenous anesthesia,the procedure of ERCP, adverse reactions and the waking time were retrospectively studied. Results A total of 45 patients in two groups under intravenous anesthesia successfully underwent ERCP . Seventeen patients ( 37. 8%) whose body weights were over 20 kg and the duration of surgery was predicted less than 30 minutes received deep sedation without airway intubation. Twenty?eight patients ( 62. 2%) with an initial weight of less than 20 kg and the duration of surgery was predicted more than 30 minutes received general anesthesia with airway intubation. In patients with deep sedation, the mean time of waking was 7. 2±6. 3 minutes, body movement reaction occurred in 1 case ( 5. 9%) and with transient decreasing of pulse blood oxygen ( beyond 95%) occurred in 2 cases ( 11. 8%) . In patients receiving endotracheal anesthesia with intubation, the mean waking time was 10. 5±8. 7 minutes without adverse reactions associated with anesthesia. Conclusion Both deep sedation and general anesthesia with airway intubation are safe for pediatric ERCP. However, general anesthesia with airway intubation is an ideal method ensuring the airway safety and oxygen supply for children less than 20 kg undergoing first?time ERCP or the duration of surgery lasting over 30 minutes.

ABSTRACT

Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.ResultsTwo groups at T0, T1 esophageal temperature no significant difference, study group t2-t6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference (P<0.05), and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).ConclusionThe surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.
