Objective To investigate the effects of forced-air prewarming combined with fluid warming on body temperature and thermal comfort in patients undergoing lobectomy.Methods Forty six patients scheduled for video-assisted thoracoscopic surgery (VATS) of lobectomy were randomized into two groups (n=23 each):warming group (group T) and the control group (group C).Forced-air prewarming combined with infusion heating was applied in the warming group,while only conventional passive warming was used in control group.The tympanic membrane temperatures were recorded before prewarming,after prewarming, during the anesthesia, the end of operation, the moment in and out of the postanesthesia care unit (PACU).Incidence of postoperative shivering, thermal comfort and the time in the PACU were recorded.Results The warming group had a slower temperature decrease at 1,2, 3 hours after operation and end of operation(P< 0.01), warming group had significantly lower incidence of hypothermia and shivering than control group(8.7% vs 56.5%, 4.3% vs 34.8%,P<0.05),and the thermalcomfort score was higher in warming group than in control group(8.52±0.94 vs 7.65±0.83,P<0.05).Conclusions Forced-air prewarming combined with fluid warming has significant clinical effects to stabilize patients` body temperature during operations,to reduce the incidence of hypothermia and shivering and to improve the thermal comfort, which provides a simple and effective temperature protection strategy for patients undergoing lobectomy.

Objective To explore the different changes of the adult cerebral blood flow with ages,different weight and gender,to summarize the changing characteristics of cerebral blood flow.Methods 360 cases of examination were divided into two groups according to gender,and were divided into five groups at different ages,and were divided into four groups according to body mass index,using TCD detector blood flow velocity.Results 196 cases of male physical examination,the mean cerebral blood flow was (969.37 ± 117.54)ml/min;the 164 females physical examination,the average cerebral blood flow was (987.76 ± 114.34)ml/min,there was no statistically significant difference (P ＞ 0.05).Different ages cerebral blood flow velocity were different,20 to 29-year-old group and the 30 to 39-year-old group had no significant difference (P ＞ 0.05) ;40 to 49-year-old group,50 to 59 years,60 to 69 years old ＞ 70 age group significantly declined compoued with the first two groups,there was significant difference (P ＜ 0.05) ;there were significant difference between the four groups (P ＜ 0.05).Overweight and obese group were significantly lower than the light and the normal group,there was a statistically significant difference (P ＜ 0.05).Conclusion TCDcan be a sensitive and accurate hemodynamic changes in the human brain,and is very important in the early diagnosis,prevention,treatment,and follow-up of cerebrovascular disease.

Objective To evaluate the diagnosis and therapy of intestinal lymphangiectasia.Methods In this study 15 patients were admitted in our hospital during recent 7 years.Clinical manifestations included hypoalbuminemia,symmetrical edema,emaciation,diarrhea and lymphopenia.Lymphangiography,lympanscintigraphy and biopsy were performed for diagnosis.Therapy conducted included conservative therapy,low-fat and medium-chain triglycerides(MCT)diet,albumin infusions,diuretics,total parenteral nutrition and octreotide.Surgical therapy ineluded thoracic duct-vein anastomasis and segmental resection.Results In this group 8 patients receiving conservative therapy were followed-up from 1.5 to 7 years(average 2.5 years).Symptoms were alleviated in 6 patients.Seven patients underwent operative therapy,among them,4 patients received thoracic duct-exterior jugular vein anastomasis and followed-up from 1 to 5 years,with symptoms mitigated in 2 patients.3 patients underwent local intestinal resection,follow-up from 1 to 3 years found one patient was cured,one was improved,and 1 patient died 3 months afterthe operation. Conclusion Intestinal lymphangiectasia is rather rare and there was no definite and effective therapy.

AIM: To observe the effects of ketamine on preventing the increase of postoperative morphine requirement induced by fentanyl.METHODS: Sixty women undergoing total abdominal hysterectomy by spinal anaesthesia were assigned to 4 groups consisting of placebo(normal saline,C),fentanyl(3 bolus of 1 ?g/kg,at 15 min intervals,F),ketamine(infusion of 15 ?g?kg-1?min-1 ketamine from the skin incision until 20 min before the end of the surgery,K),ketamine and fentanyl(infusion of 15 ?g?kg-1?min-1 ketamine from the skin incision until 20 min before the end of the surgery plus 3 bolus of 1 ?g/kg fentanyl,at 15-min intervals,FK).The cumulative morphine consumption,pain score,and adverse effects(nausea, vomiting,hallucination,dizziness and itching) were recorded at 1,3,6,12,24,48 h postoperatively.RESULTS: There were no significant differences in age,weight,duration of surgery and the post-operative sensory block time.The cumulative morphine consumption in group F was significantly higher than those in group C at 3,6,12 h postoperatively(P

Objective To investigate the incidence,diagnosis,treatment and prognosis of abnormal lymphatic vessels in intestinal lymphangiectasia (IL) patients complicated by portal vein hypertension.Methods General information,clinical manifestations,laboratory tests,endoscopy and pathological examination,the results of direct and nuclide lymphangiography,treatment and prognosis of seven IL patients complicated by portal vein hypertension were retrospective analyzed.Results Among seven IL patients complicated by portal vein hypertension,there were five cases with abnormal lymphatic vessels and two cases were merely secondary to portal vein hypertension.The main symptoms were edema,abdominal distension and diarrhea.The results of laboratory tests mainly were lymphocytopenia (0.3× 109 to 1.7 × 109/L),hypoalbuminemia (16.0 to 27.8g/L) and hypoglobulinemia (13.2 to 17.7 g/L).Under endoscope,mucosal edema,chronic inflammatory reaction,intestinal villi spot and patched white nodular changes and polyp-like changes appeared.For treatment,the low-fat with medium-chain triglyceride diet and symptomatic support was the basic treatment.The condition could be relieved by surgical remission of abnormal lymphatic vessels or partial small-bowel resection.If the etiological factors could not be removed,the therapeutic effect was poor in the patients merely secondary to portal vein hypertension.Conclusion The suspicious IL patients complicated by portal vein hypertension need further examination to explore whether abnormal lymphatic vessels existed,and to provide evidence for surgical intervention.

Objective To summarize the clinical characteristics of liver cirrhosis complicated with chylous ascites.Methods From July,2007 to November,2012,patients diagnosed as liver cirrhosis complicated with chylous ascites were retrospectively analyzed.Analyze the etiology,liver function,ascites,imaging examination,treatment options and progonsis of these patients.Differences in measurement data were compared with U test.Results A total of 34 cases were enrolled,male 27 cases and female seven cases,average age (51.7±12.5) years old.Hepatitis B (20/34,58.8％) was the most common etiology of liver cirrhosis.Child-Pugh grading was grade B (26 cases) and C (eight cases).The appearance of aseites of 17 cases was chylous and the serm-ascites albumin gradient (SAAG) was 18.8 (2.6 to 32.5) g/L.The SAAG of 27 cases (84.4％) was no less than 11.0 g/L.The ascites triglyceride (TG) level was 2.94 (0.26 to 16.75) mmol/L,the TG of 27 cases (84.4％) was no less than 1.25 mmol/L.The level of TG (2.66(0.26 to 16.75) mmol/L) of patients with SAAG over 11.0 g/L was significantly lower than that of SAAG lower than 11 g/L (7.07(2.26 to 15.67) mmol/L,U=24.00,P=0.02).The lymphatic scintigraphy indicated that imaging agent leaked into peritoneal cavity in 29 cases (85.3 ％).Direct lymphangiography revealed lymphatic vessel structure abnormality in 15 cases (60 ％).Twelve patients received conservative treatment and four patients were effective,13 patients accepted peritoneal-venous shunting and 12 patients were effective,11 patients with microsurgical treatrnent and seven patients were effective.Conclusions Lymphatic struture is a possible cause of cirrhosis patients with chylous ascites.The characteristics of chylous ascites in cirrhosis patients are still the same as the characteristics of portal hypertension ascites.The SAAG remarkably increases,and the the level of SAAG probably depends on TG level.Lymphoscintigraphy has great value on the determination of the presence of ascites.And the direct lymphangiography could help to reveal lymphatic vessel structure abnormality.

Objective:To explore the clinical features of Stewart-Treves syndrome in postoperative patients of breast cancer.Methods:The clinical data of 11 patients with Stewart-Treves syndrome after breast cancer surgery in Beijing Shijitan Hospital from Aug 2008 to Sep 2016 were retrospectively analyzed.Results:All the 11 patients were female , age ranging from 44 to 78 years.The main clinical manifestations included multiple skin and subcutaneous nodules , scattered red or purplish red rashes in the lymphedematous upper limbs, and sometimes in the chest wall. MRI showed multiple short T2 signal soft tissue nodules in skin and subcutaneous soft tissue. Histopathology showed heterogeneous endothelial cell-derived malignant tumor. Immunohistochemical staining showed positive CD31, CD34 and D2-40. These 11 patients had skin and subcutaneous tumor excision and biopsy, 4 had shoulder amputation, 4 received postoperative adjuvant chemo plus or radiotherapy. As of Feb 2020, 1 patient was alive, 9 died and 1 lost follow-up.Conclusions:Stewart-Treves syndrome is a rare complication of breast cancer, with poor prognosis and high mortality.

OBJECTIVETo discuss the diagnosis and therapy of chylous reflux and external chylous fistula.

METHODSAll of 6 patients were diagnosed with direct lymphagiography, lymphscintigraphy. Among them, 2 patients received CT after direct lymphagiography. Retroperitoneal lymphangiectomy plus lymph-vein shunting was performed in 5 patients, and retroperitoneal lymphangiectomy in 1 patient.

RESULTSThe 6 patients were followed up from 6 months to 6 years. In 5 patients, chylous cysts disappeared and chylous fistula closed, and in 1 patient, chylous fistula didn't cicatrize, and chyle still leak out from the scrotum.

CONCLUSIONSRetroperitoneal lymphangiectomy plus lymph-vein shunting has curative effect on chylous external fistula of the lower extremity and genitalia, but it has the chance to not obstruct all paths of chylous reflex.

Objective: To study the clinical effects of liposuction combined with lymphatico-venous anastomosis for treatment of secondary lymphedema of the lower limbs. Methods: A retrospective analysis was performed for 49 patients who had undergone liposuction combined with lymphatico-venous anastomosis to treat secondary lymphedema of the lower limbs at Department of Lymph Surgery, Beijing Shijitan Hospital from November 2013 to February 2015.All patients were female aging from 31 to 70 years with median age of (52±10)years.All patients had history of pelvic surgery.There were 32 cases with cervical carcinoma, 11 cases with endometrial cancer, 1 case with ovarian cancer who accepted radical hysterectomy, 2 cases with benign tumor who accepted resection, 2 cases accepted inguinal lymph node dissection, 1 case with rectal cancer accepted radical resection.There were 30 cases with history of radiation therapy and 23 cases with history of erysipelas recurrent((2.1±3.9)/year). The limb swelling degree in preoperative and postoperative patients was explored using one-way analysis of variance with replicate measures and paired sample t-test. Meanwhile the incidence of lymphogenous infection was used as an evaluation of operation efficacy. Results: The mean lower limb circumference difference at 7 days, 6 months and 12 months was (0.17±1.36)cm, (1.25±1.62)cm and(1.58±1.56)cm, respectively, which was significantly decreased compared with preoperative((4.92±2.16)cm) (t=-5.712, -5.777, -5.765; all P<0.01). The mean lower limb volume difference at 7 days, 6 months and 12 months was (522±799)ml, (726±973)ml and (889±895)ml, respectively, which was significantly decreased compared with preoperative((2 729±1 335) ml)(t=-5.905, -6.093, -5.777; all P<0.01). The incidence of erysipelas was 0.0(0.0, 0.0)/6 months within 6 months after operation and 0.0(0.0, 0.0)/6 months within 6-12 months after operation, which was significantly lower than that before operation(0.0(0.0, 2.0)/year). The feeling of tightness and heaviness of the limb was significantly improved compared with preoperative. Conclusion Liposuction combined with lymphatico-venous anastomosis is an effective method for the treatment of secondary lymphedema of the lower limbs.
