Objective To review the value of imaging assessment for perioperative period of liver transplantation. Methods The related literatures in recent years were reviewed, and the applications of various kinds of radiological techniques in perioperative period of liver transplantation and radiological strategies of major complications after liver transplantation were summarized. Results Transplantation has become an effective option for treatment of patients with irreversible severe liver dysfunction. Radiological assessment supplies prompt and accurate information for clinic to increase the success rate and reduce the complications. So it plays an irreplaceable role. Conclusions Radiology assessment is important for screening donors and recipients before liver transplantation， following up and monitoring the complications. The doctor of imaging department could grasp the different imaging appearance in perioperative period of liver transplantation.
ObjectiveTo evaluate and summarize the perioperative management experience of living related liver transplantation (LRLT). MethodsA retrospective analysis was made in perioperative management of 13 cases undergoing LRLT (15 times operation, including 2 cases of liver retransplantation) in our department from January 2001 to December 2002. ResultsAll the operations were successful. All the 13 donors were followed up regularly, 12 donors were uneventfully recovered after operation and 1 donor suffered from bile leakage due to T tube. The survival rate of recipients, who achieved longterm survival at 2 months to 2 years, was 92.3%(12/13); the survival rate of graft was 86.7%(13/15). One adult recipient with Wilson’s disease died of serious rejection on the 72nd day postoperatively. Two cases suffered from embolism of hepatic artery, one case received reduced size cadaveric liver retransplantation, the other case received liver retransplantation from cadaver, and they both achieved longterm survival after retransplantation. The other complications included: 1 case of serious rejection, 2 cases of ARDS, 6 cases of infection of microbe, 7 cases of serious hydrothorax, 1 cases of leakage of biliary tract, and so on. ConclusionPerfect preoperative management, which composes one of the key parts of LRLT, is critically important for both donor and recipient.
Objective To introduce the results and strategy of perioperative management undergo coronary artery bypass grafting (CABG) for patients older than 70. Methods One hundred and twenty one patients, 93.4%(113/121) of whom was complicated with other diseases, were retrospectively studied. Off-pump CABG (OPCAB) was used in 80 cases (66.1%). For the rest patients with severely compromised heart function or small target vessel with diffuse lesion, conventional CABG (CCABG) was selected. Left internal mammary artery (LIMA) was harvested leaving pleural cavity intact and grafted to left anterior descending artery (LAD). Saphenous vein(SV) was utilized for other anastomoses. Transit-time flowmeter (TTFM) was utilized to make sure that grafts were patent with satisfactory blood flow. Procedure of sternotomy and chest closure was carefully performed to decrease the complication of mediastinitis. Adequate nutrition and gradually increased physical activity were encouraged for "fast-track". Results Grafts were 3.08±0.75 for CCABG and 2.24±0.82 for OPCAB . LIMA was used in 90.9%(110/121) patients. One patient receiving emergency operation died of multiple organ failure syndrome resulting in mortality of 0.8%. The incidence of complication was 3.3%(4/121). The others recovered smoothly without any complication. Intubation time of OPCAB(10.04±5.68 h) was significantly shorter than that of CCABG(21.46±14.54 h). Patients were discharged within 12.22±5.56 days after operation. Conclusion Good short term result, namely low incidence of mortality and complication, could be obtained in patients older than 70 who underwent CABG through meticulous perioperative management.
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.
ObjectiveTo explore the nursing experience of preoperative treatment for urethral injury with ureteroscopic urethral realignment. MethodsThe key points of the nursing experience of preoperative treatment for 58 cases of urethral injury with ureteroscopic urethral realignment were retrospectively analyzed. The patients were treated between January 2008 and December 2012. ResultsUrethra catheterization of the 58 patients receiving the ureteroscopic urethral realignment was all successful. The catheter was extracted 4-8 weeks after the treatment, and then the urethra was dilated for two years. All patients had normal urination without any surgery complications during the 5-28-month clinical follow-up. ConclusionUrinary tract infections can be prevented effectively under professional and meticulous preoperative treatment. The incidence of urethral stricture can be reduced greatly. The quality of the patients' life can be improved a lot.
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.
Perioperative management of 58 hypertensive patients suffering from surgical disease is reported. We emphasize that before operation the blood pressure should be adequately controlled, and heart function promoted. It is safer that the diastolic pressure is controlled under 14 kPa before operation. During operation we strictly observe the change of the blood pressure and manage it in time. Analgesic and antihypertensive agents are used after operation.
Vague preoperative localization and ectopic parathyroid often lead to the failure of operation in primary hyperparathyroidism. From Jun 1989 to March 1998, 11 cases of primary hyperparathyroidism had been treated surgically in the general surgery department of our hospital. Of them, 10 cases were operated successfully with the pathological diagnosis of adenoma and one parathyroid removed was reported normal. Preoperative localization, the knowledge of ectopic parathyroids, careful exploration during operation and the postoperative medical treatment are important for the perioperative management. Postoperative followup has emphasized to benefit the treatment in primary hyperparathyroidism.
