Objective To explore the effect of self-assessment of pain in perioperative pain management of total knee arthroplasty (TKA). Methods A total of 140 patients undergoing TKA from March 2016 to March 2017 were randomly divided into the control group and the trial group. The patients in the two groups were received the same education relating to pain knowledge. The intensity of pain was assessed by nurses in the control group, while in the trial group, it was assessed by patients themselves. According to the assessment of pain, treatments were given to both groups. Time of pain assessment, types and frequencies of temporary rescue medicine, pain intensity, the score of Self-efficacy for Rehabilitation Outcome Scale (SER) and the range of motion (ROM) of knee were observed and recorded. Results There were 132 patients who completed the final observation, with 67 in the trial group and 65 in the control group. There were significant differences between the two groups in evaluation time of pain (t=–2.736, P=0.007), types and frequencies of temporary rescue medicine (χ2=10.276, P<0.05), the overall postoperative pain score (Z=–2.146, P=0.032), average hospitalization time after surgery (t=–2.468, P=0.015), SER scores 7 days after surgery (F=2.390, P=0.018) and 14 days after surgery (F=3.427, P=0.001), and ROM at the postoperative day 7 (F=2.109, P=0.037); there were no significant differences in postoperative daily pain scores (Z=–1.779, P=0.077), SER scores at the postoperative day 3 (F=1.010, P=0.314), ROM at the postoperative day 1 (F=1.319, P=0.189) and day 14 (F=1.603, P=0.111). Conclusion Self-assessment of pain can motivate TKA patients to take part in pain management, and more accurate response to the pain intensity will help to optimize the management of perioperative pain and reduce the workload of the health staff, thereby contributing to enhanced recovery.
ObjectiveTo summarize the perioperative blood management strategies for joint arthroplasty. MethodsThe literature concerning preoperative, intraoperative, and postoperative blood management was reviewed and summarized. ResultsAt present, a variety of blood management and conservation strategies are available. Preoperative strategies include iron supplementation, erythropoietin (EPO), and preoperative autologous donation (PAD). Intraoperative options include acute normovolemic hemodilution (ANH), antifibrinolytics, and the use of a tourniquet. Postoperative strategies include the use of reinfusion systems and guided transfusion protocols. Preoperatively, administration of either simple EPO or a combination of EPO and PAD can be efficacious in anemic patients. Intraoperatively, tourniquet use and tranexamic acid can effectively control bleeding. Postoperatively, appropriate transfusion indications can avoid unnecessary blood transfusions. ConclusionPerioperative blood management strategies for joint arthroplasty should be integrated for the individual patient using a variety of ways to reduce perioperative blood loss and blood transfusion, and promote the rehabilitation of patients.
OBJECTIVE: To investigate the efficacy of different flaps in the treatment of skin defect of hell. METHODS: Forty-six patients with skin defect of hell were adopted in this study. There were 39 males and 7 females, 29 years old in average. Six different flaps were applied in the reconstructive operation, 14 plantaris medialis flaps, 4 flexor digitorum brevis muscle flaps, 3 abductor hallucis flaps, 7 latissimus dorsi flaps, 16 distal medialis flaps of leg pedicled with the cutaneous branch of posterior fibial artery, 2 foot dorsum flaps. RESULTS: All the flaps survived, primary healing of the wound in 45 cases and secondary healing in 1 case. Followed up for 3 months to 4 years, 43 patients obtained good flap sensation, the function of weight bearing were satisfied in 43 patients. CONCLUSION: The six different flaps should be applied according to patient’s condition individually. The sensation of flap is very important to the function of weight bearing.
Objective To investigate the changes of renal medulla aquaporin 2 expression and morphological changes of epithelia of collecting tube after bile duct recanalizaiton operation. Methods Thirty rats were divided into two groups randomly. Common bile duct ligation was performed on 20 experimental rats with silicon tubes 2 mm in extre-diameter, and sham operation on the other 10 rats. Seven days later, bile duct recanalizaiton was performed on obstructive jaundice group and sham operation on contrast group. Experimental rats were divided into two subgroups randomly. Half of them were killed immediately and the others would be killed 24 hours later. Serum of each rat was collected to detect hepatic function and renal function. Renal medulla was fixed for microscopic examination and was kept in the -80 ℃ refrigerator for aquaporin 2 expression measurement by Western blot technique. Results All of the animals accomplished the experiment smoothly. Golden ascites were found in the rats of obstructive jaundice group. Twenty-four hours after recanalization, serum bilirubin levels decreased 〔(45.95±8.39) μmol/L〕, P＜0.01, and there was no significant change in blood urine and creatine level. Compared with sham operation group (21 966.20±1 544.70), expression of aquaporin 2 decreased significantly after common bile duct ligation in obstructive jaundice group (15 665.30±1 181.85), P＜0.01. After recanalizaion, the expression of aquaporin 2 in obstructive jaundice group increased (19 490.80±4 239.32), P＜0.01. Conclusion Common bile duct obstruction would lead to epithelium injury of renal collecting tube, and down regulate the aquaporin 2 expression.
Objective To determine the total blood loss and hidden blood loss associated with surgery for lumbar spinal stenosis and to identify risk factors for blood loss. Methods From September 2002 to July 2006, the cl inical data from 138 patients with lumbar spinal stenosis undergoing initial operation were analysed prospectively. There were 44 males and 94 females, aging 56-78 years (mean 66.7 years). A simple posterior lumbar spinal decompression was used in 26 cases;posterior spinal canal decompression, interbody distraction Cage, and bone graft between transverse process was used in 54 cases; pedicle screw fixation, posterior decompression and bone graft between transverse process was used in 32 cases; posterior decompression, pedicle screw fixation, interbody Cage, and graft between transverse process was used in 26 cases . Before operation, 23 patients took aspirin, and after operation 15 patients had gastrointestinal bleeding. Intraoperative blood loss was calculated by the aspirator and observed blood loss intraoperation. The whole estimated blood loss was calculated according to the level of hemoglobin, blood volume and blood transfusion at the time of admission and after 3 and 4 days of operation. Results The blood loss intraoperation was (485.51 ± 143.75) mL. The estimated blood loss was (1 218.60 ± 306.86) mL, which was significantly higher than the intraoperational blood loss (P lt; 0.001). There was significant difference between the estimated blood loss and observed blood loss during surgeries (P lt; 0.001). There were significant differences in the estimated blood loss and observed blood loss during surgery between patients treated with aspirin and without aspirin (P lt; 0.001), between patients with gastrointestinal bleeding and whiout gastrointestinal bleeding (P lt; 0.001). Conclusion The total blood loss after surgery for lumbar spinal stenosis is much greater than that of observed intra-operation. The type of surgery, treatment with aspirin and gastrointestinal bleeding or ulceration can all independently increase blood loss.
ObjectiveTo evaluate the effect of airway management drugs on the respiratory function and postoperative recovery of patients who had moderate or severe chronic obstructive pulmonary diseases(COPD) undergoing an open chest surgery. MethodThere were a total of 22 patients suffering from both lung cancer, esophageal cancer or gastroesophageal junction carcinoma and moderate to severe COPD(of which there were 16 males and 6 females; accepting traditional operation 5 cases and minimally-invasive operation 17 cases; lung cancer 16 cases, esophageal cancer 4 cases and gastroesophageal junction carcinoma 2 cases as the observation group). To statistic the respiratory function and arterial blood gas analysis before and after treating with airway management drugs. And compare the postoperative pulmonary complications(PPCs) and hospital-stay with 50 patients who have no COPD(of which there were 34 males and 16 females; accepting traditional operation 17 cases and minimally-invasive operation 33 cases; lung cancer 35 cases, esophageal cancer 11 cases and gastroesophageal junction carcinoma 4 cases as the control group). ResultThere was a statistical difference of forced expiratory volume in one second(FEV1), forced vital capacity(FVC) and maximal voluntary ventilation(MVV) after the above treatment by 7 to 10 days and comparing with prior treatment(P<0.05). Partial pressure of oxygen(PaO2) increased with no statistical difference(P>0.05) while PaCO2 decreased with a statistical difference(P<0.05）. Comparing with patients without COPD, the incidences of PPCs and postoperative hospital stay were of no statistical difference(P>0.05). ConclusionPatients with moderate or severe COPD with airway management drugs(antibiotics,glucocorticoids, bronchodilators and phlegm dissolving agent) in perioperative period could improve the respiratory function and operation tolerance effectively, reduce the incidence of PPCs and shorten postoperative hospital stay.
Objective To explore the application effect of process optimization in perioperative venous access management. Methods A total of 205 general surgery patients in the Operating Room of Cheng Du Shang Jin Nan Fu Hospital, West China Hospital of Sichuan University from April to May 2018 were selected as the control group, and 205 general surgery patients from June to August 2018 were selected as the observation group. The traditional management process was used in the control group, and the process optimization management was performed in the observation group. The establishment of venous access and related complications between the two groups of patients, as well as the satisfaction of patients and staff before and after the process optimization were compared. Results There was no significant difference in gender, age, education level, operation type, anesthesia method, operation duration, or intraoperative intravenous infusion channels between the two groups of patients (P>0.05). There was no statistically significant difference in gender, age, educational background, job title, job nature, or working years of the staff participating in the satisfaction survey before and after the process optimization (P>0.05). The rate of repetitive venous puncture (15.61% vs. 58.05%) and the idelness ratio of the intraoperative indwelling needle approach (10.73% vs. 52.20%) in the observation group were lower than those of the control group, and the differences were statistically significant (P<0.05). There was no statistically significant difference in the incidence of tube blockage, detubation, or phlebitis/exudation between the two groups (P>0.05). After process optimization, patient satisfaction (22.91±3.43 vs. 17.44±4.90) and staff satisfaction (28.17±2.56 vs. 20.65±3.71) were higher than before optimization, and the differences were statistically significant (P<0.05). Conclusions The process optimization of venous access management for perioperative patients can effectively reduce the rate of venous repeated venipuncture and the idelness ratio of the intraoperative indwelling needle approach, reduce invasive operations on patients, reduce the ineffective work of nurses, avoid the waste of medical resources such as manpower and materials, and improve the satisfaction of patients and staff. It is worthy of promotion and application.
ObjectiveTo summarize perioperative management experience of 16 patients undergoing surgical correction of anomalous origin of the left coronary artery from pulmonary artery (ALCAPA). MethodsWe performed a retrospective analysis of 16 patients who received surgical correction of ALCAPA between January 2005 and December 2013 in Cardiovascular Center of Children's Hospital of Fudan University. There were 6 males and 10 females with their age ranging from 2 months to 13 years (mean age of 23.25±0.63 months) and body weight ranging from 5 to 30 kg (mean body weight of 19.77±0.75 kg). All the patients underwent direct implantation of the anomalous coronary artery into the ascending aorta, and received comprehensive management regarding left ventricular ejection fraction (LVEF), heart rate, blood pressure, arterial blood gas, urinary volume, blood lactic acid and central venous pressure. ResultsPostoperative complications were low cardiac output syndrome (LCOS) in 9 patients (including intractable LCOS in 2 patients) and arrhythmia in 1 patient. One patient with intractable LCOS and arrhythmia died postoperatively with the mortality of 6.25%. Cardiopulmonary bypass time was 85-260 (135.61±35.01) minutes, aortic cross-clamping time was 40-97 (57.32±16.02) minutes, mechanical ventilation time was 34-187 (106.34±41.62) hours, length of CICU stay was 2-21 (8.13±5.02) days, and hospital stay was 12-51 (22.14±5.00) days. Postoperative LVEF and left ventricular fractional shortening were significantly higher than preoperative values (P < 0.05). ConclusionKey points for successful surgical correction of ALCAPA include meticulous perioperative management, preoperative heart function improvement, prevention of postoperative complications and use of new techniques.
Objective To explore the perioperative management of the coexisting diseases for the elderly patients with gastric cancer. Methods The clinical data of perioperative management for coexisting diseases in 528 patients with gastric cancer over 70 years old treated in the First Affiliated Hospital of China Medical University from March 1980 to November 2008 were analyzed retrospectively. Results The main coexisting diseases included cardiovascuclar disease (259 cases, 49.05%), respiratory disease (161 cases, 30.49%), diabetes (72 cases, 13.64%). Adjusting blood pressure and blood glucose, improving cardiopulmonary function, and hepatic and renal function were mainly given. The common postoperative complications included intestinal obstruction (10 cases), pneumonia (10 cases), reflux esophagitis (9 cases), functional evacuation disorder of gastric remnant (7 cases), and anastomotic leakage (5 cases). Ten patients died during perioperative period: 6 died of heart and lung failure, 2 of acute myocardial infarction, 1 of anastomotic leakage, 1 of intestinal obstruction. Conclusions The common coexisting diseases in the elderly patients with gastric cancer are hypertension， bronchitis and diabetes. Complete assessment of the patient’s general health before operation and intensive perioperative management of the coexisting diseases not only can decrease the risk of surgical procedures， but also decrease the incidence of complication and perioperative mortality.
