Objective To compare the hemostatic effects and tourniquet induced side reactions of 2 different tourniquets in internal fixation of bilateral tibia and fibula fracture. Methods Between May 2008 and May 2010, 21 patients with bilateral tibia and fibula fracture were treated and randomly divided into 2 groups according to left and right l imbs. When steel plate fixation was performed, equil ibrium pressure pneumatic tourniquet (EPPT group) and common tourniquet (common group) were used to staunch the flow of blood respectively. The time of using tourniquet was 60 minutes, and the hemostatic pressure was 50 kPa. There were 12 males and 9 females with an age range of 17 to 58 years (mean, 32.5 years). Injurywas caused by traffic accident in 9 patients, by heavy pound in 6 patients, and fall ing from height in 6 patients. According to X-ray calssification, there were 15 cases of simple type, 3 cases of butterfly type, and 3 cases of comminuted type in EPPT group; there were 13 cases of simple type, 5 cases of butterfly type, and 3 cases of comminuted type in common group. The time from injury to operation was 3 to 72 hours (mean, 37.5 hours). Results The time of using tourniquet was (95.30 ± 4.19) minutes in EPPT group and (94.11 ± 5.16) minutes in common group, showing no significant difference (P gt; 0.05). All the incision of 2 groups healed by first intension. After 2 weeks of operation in common group, peroneal nerve injury occurred in 3 cases, and was cured by supporting nerve for 3 months; bl ister occurred in 1 case and was cured after dressing change for 3 weeks; and the injury rate was 19%. No compl ication occurred in EPPT group with an injury rate of 0. There was significant difference in the injury rate between 2 groups (P lt; 0.05). The hemostatic effects were excellent in 19 cases and good in 2 cases of EPPT group, were excellent in 10 cases, good in 3 cases, and poor in 8 cases of common group; the excellent and good rate were 100% and 61.9% respectively, showing significant difference (P lt; 0.05). All patients were followed up 3-24 months. Fracture healed without nonunion and deformity union in 2 groups. Conclusion Comparing to common tourniquet, the EPPT can provide good bloodless field, lower hemostatic pressure, and less tourniquet compl ication.
ObjectiveTo investigate the application value of totally laparoscopic associating liver tourniquet and portal ligation for staged hepatectomy (ALTPS) using the anterior approach technique for hepatocellular carcinoma (HCC) with hepatitis B cirrhosis. MethodsIn September, 2014, a patient suffered cirrhotic hepatocellular carcinoma in the right liver scheduled for two-stage liver resection, in whom the future liver remnant (FLR) was considered too small (FLR/standard liver volume:29.1%, FLR/body wight:0.49%). In the first stage, using totally laparoscopic technique, a tourniquet was placed around the parenchymal transection line on the Cantlie's line via an anterior approach through retrohepatic tunnel for staged right hepatectomy, and the right portal vein was ligated. In the second stage, totally laparoscopic right hemihepatectomy was carried out on 10 days after the first-stage operation that achieved sufficient hypertrophy of the FLR. ResultsThe FLR on postoperative day 4 of the first stage increased from 301.48 to 496.45 mL (FLR/standard liver volume:47.9%, FLR/body wight:0.81%), with a 64.67% hypertrophy. And the FLR on postoperative day 8 of the first stage increased to 510.96 mL (FLR/standard liver volume:49.3%, FLR/body wight:0.84%), with a 69.48% hypertrophy. The remnant liver volume on postoperative day 5 of the second stage increased to 704.53 mL. The duration of the first stage was 180 min, intraoperative blood loss was 50 mL, and patient did not received a blood transfusion. The duration of the second stage was 220 min, intraoperative blood loss was 400 mL, and patient did not required a blood transfusion. No serious complications happened. The patient was discharged on 7 days after the second stage. ConclusionsAs a effective, safe, simple, and "non-touch" technique which provided a less aggressive modification of the ALPPS procedureto achieve oncological efficacy, the totally laparoscopic ALTPS using the anterior approach technique also could achieve sufficient hypertrophy of the FLR in several days. A proper expansion of the indications for the procedure is safe and feasible in HCC patients with cirrhosis.
Objective To evaluate the effect of pneumatic tourniquet on perioperative period of total knee arthroplasty (TKA). Methods The perioperative period data of 116 patients over 60 years old with severe knee osteoarthritis treated with TKA between January 2018 and January 2019 were retrospectively analyzed. According to whether pneumatic tourniquet was used during operation, the patients were divided into trial group (49 cases, pneumatic tourniquet was not used during operation) and control group (67 cases, pneumatic tourniquet was used during operation). There was no significant difference in gender, age, body mass index, lesion side, disease duration, and preoperative hemoglobin between the two groups (P>0.05). The operation time, actual total blood loss, overt blood loss, hidden blood loss, and percentage of hidden blood loss, knee swelling at 3 days after operation, and range of motion of knee at 2 weeks after operation were recorded and compared between the two groups. Results The operation time of the trial group was significantly longer than that of the control group (t=14.013, P=0.000). The actual total blood loss, hidden blood loss, and percentage of hidden blood loss in the trial group were significantly lower than those in the control group (P<0.05); there was no significant difference in the overt blood loss between the two groups (t=−1.293, P=0.200). The knee swelling degree in the trial group was significantly slighter than that in the control group at 3 days after operation, and the range of motion of knee in the trial group was significantly better than that in the control group at 2 weeks after operation (P<0.05). Conclusion Pneumatic tourniquet can reduce the operation time of TKA significantly. However, it may increase the hidden blood loss and knee swelling, and negatively impact the recovery of knee function in the early postoperative stage of TKA.
ObjectiveTo investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique.MethodsBetween July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction.ResultsThe operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant (P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension.ConclusionUsing WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient’s own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.
Objective To explore the value of wide-awake local anesthesia no tourniquet (WALANT) technique in the treatment of acute Achilles tendon rupture. MethodsIn a prospective randomized controlled trial, 48 patients with acute Achilles tendon rupture who met the criteria between March 2020 and October 2020 were randomly divided into two groups according to 1∶1 distribution, with 24 cases in each group. The study group used WALANT technique and the control group used epidural anesthesia with tourniquet for channel-assisted minimally invasive repair (CAMIR). There was no significant difference between the two groups in gender, age, injured side, cause of injury, distance from broken end of Achilles tendon to calcaneal tubercle, and time from injury to hospitalization (P>0.05). The operating room use time (from patients entering the operating room to leaving the operating room), intraoperative blood loss, hospital stay, and the highest pain score [using Numerical Rating Scale (NRS)] during operation and at 1 day after operation were recorded and compared between the two groups. The tourniquet adverse reactions in the control group were recorded. The functional recovery was evaluated by the scoring method of American Orthopedic Foot and Ankle Society (AOFAS) at 12 months after operation. ResultsThe operation was successfully completed in both groups. The operating room use time and hospital stay in the study group were significantly less than those in the control group (P<0.05), but the difference in the intraoperative blood loss between the two groups was not significant (t=0.429, P=0.670). There was no significant difference in the highest NRS score during operation between the two groups (t=1.671, P=0.101); the highest NRS score in the study group at 1 day after operation was significantly lower than that in the control group (t=−6.384, P<0.001). In the control group, 13 patients had different degrees of tourniquet adverse reactions, including tourniquet regional pain, local swelling, blisters, thigh numbness, and discomfort. The patients in both groups were followed up 12-18 months, with an average of 13.9 months. The motor function of all patients returned to normal at 12 months after operation. The difference in AOFAS scores between the two groups was not significant (t=0.345, P=0.731). There was no complication such as sural nerve injury, local infection, and secondary rupture in both groups. ConclusionThe application of WALANT combined with CAMIR technique in the treatment of acute Achilles tendon rupture has good anesthetic and effectiveness, avoids the adverse reactions of tourniquet, and reasonably saves social medical resources.
