ObjectiveTo clarify the effectiveness of preoperative pulmonary rehabilitation (PPR) and provide evidence for the application of PPR on lung cancer patients by meta-analysis.MethodsAccording to inclusion and exclusion criteria, literatures related to PPR on lung cancer patients were retrieved from major databases between the date of establishment of each database and January 2019, and then data required were extracted from the selected literatures. Meta-analysis was conducted by RevMan 5.0.ResultsTwelve randomized controlled trials were involved in meta-analysis, including 658 patients who were well-diagnosed and prepared for surgery, with 307 patients in the PPR group and 351 patients in the control group. The results of the meta-analysis showed that in the PPR group, the pulmonary function including forced vital capacity [MD=0.31, 95%CI (0.21, 0.42), P<0.01], forced expiratory volume in one second [MD=0.27, 95%CI (0.20, 0.34), P<0.01] and activity tolerance including 6-minute walk distance [MD=50.55, 95%CI (35.98, 65.13), P<0.01] were significantly better than the control group, and the postoperative complication rate was lower ［MD=0.28, 95%CI (0.18, 0.43), P<0.01］, postoperative hospital stay was shorter [MD=–2.09, 95%CI (–2.41, –1.77), P<0.01].ConclusionsA period of PPR on lung cancer patients can improve postoperative pulmonary function and activity tolerance, and reduce postoperative complications and hospital stay, which is beneficial to postoperative recovery.
ObjectiveTo analyze the current situation of day surgery patients’ withdrawal from hospitalization, and put forward reasonable and effective measures and suggestions.MethodsDescriptive statistical analysis and trend chi-square test were conducted on the hospitalization withdrawal rate of day surgery in the Day Surgery Ward of the Second Affiliated Hospital Zhejiang University School of Medicine from 2012 to 2020. The reasons for hospitalization withdrawal and the operation methods of withdrawn cases from 2019 to 2020 were descriptively analyzed.ResultsFrom 2012 to 2020, the hospitalization withdrawal rate of day surgery decreased from 4.48% to 2.19%, with a significant decrease and a linear downward trend (χ2trend=138.500, P<0.001). From 2019 to 2020, patient factor was the most important reason for hospitalization withdrawal of day surgery, accounting for 79.72%; secondly, long waiting time for surgery, abnormal examination results, inadequate preoperative evaluation, medical insurance reimbursement, epidemic situation in 2020 and other reasons had affected the patients’ hospitalization withdrawal of day surgery to varying degrees. Endoscopic lithotripsy accounted for the largest proportion (210 cases, accounting for 20.87%) in the withdrawn procedures from 2019 to 2020, followed by minimally invasive rotary resection for breast lesions (126 cases, accounting for 12.52%).ConclusionImproving preoperative evaluation, strengthening preoperative communication, implementing efficient medical treatment, and shortening the waiting time for surgery can reduce the rate of hospitalization withdrawal of day surgery.
ObjectiveTo summarize the clinical features and imaging features of CT in the omental torsion, and in order to reduce the misdiagnosis and missed diagnosis rate of imaging features.
MethodsThe data of 16 cases of omental torsion (secondary 15 cases, primary 1 case) and 286 cases of acute appendicitis (eliminated the subhepatic and retroperitoneal ectopic appendix) in our hospital from 1998 to 2014 were retrospectively analyzed.
ResultsEleven cases of omental torsion suffered from the shifting pain in right lower quadrant. No obvious shifting abdominal pain was observed in other 4 cases whose main manifestations were abdominal tenderness and rebound tenderness around umbilicus. The patient of the remaining 1 case had enclosed mass in the area of left groin with pain and suffered from continuous periumbilical pain. Abdominal spiral CT examination was performed in 16 patients before operation. Increased signal intensity of globular soft tissue, which deviating from McBurney's point, was found at level of distal umbilicus by preoperative spiral CT in 13 cases. One case of omental torsion associated with ncarcerated inguinal hernia was missed.
ConclusionsOmental torsion manifests chiefly shifting pain in right lower quadrant, abdominal tenderness, and rebound tenderness around umbilicus. It is easily confused with appendicitis. Abdominal spiral CT should be chosen as a preferred means in preoperative diagnosis of omental torsion.
ObjectiveTo investigate the preoperative psychological state of patients with pulmonary nodules in order to make the content of the education more "individualized and humanized".MethodsWe conducted a consecutive questionnaire study for 107 patients who were planning to undergo pulmonary resection surgery from May 2018 to July 2018 in our department. There were 54 males and 53 females with an average age of 56.8±11.2 years. The questionnaire content included two parts: personal basic information and 20 questions about surgery, complications, follow-up and hospitalization expense.ResultsThere were 60.7% of the patients diagnosed with pulmonary nodules by CT scan during physical examination, and 52.3% of the patients had strong will to undergo pulmonary surgery to resect nodules; 64.5% of patients wanted doctors to tell them the extent of the disease and whether the tumor could be cured by surgery, and 30.0% of patients concerned whether chief surgeon would complete the whole surgery. The surgery risk and postoperative complications were ignored by patients easily (5.6% and 14.9% respectively). The hospital expenses were not the primary concern of patients. Only 1.9% of patients believed that doctors used nonessentials which deliberately led to increased costs. Network follow-up was accepted by most patients (94.4%).ConclusionIt will contribute to improve preoperative education rationality and effectiveness by understanding true psychological state of patients.
42 cases of hyperthyroidism had been operated from 1990-1993.In the preoperative treatment,antithyroid drugs were used togather with thyroxine.Some advantages have been observed,which are better than drugs were used togather with thyroxine.Some advantages have been observed,which are better than thoes of the usual preoperative preparaton.①Patient can be prepared to a complete euthyroid state.②The vascularity of the gland can be reduced to a least degree so that the operative risk of bleeding is will small.③The serum thyroid hormone will not be raised,therefore no thyroid crisis occurs.
Partial or complete blockage of the bile outflow tract by extrahepatic cholangiocarcinoma often leads to jaundice, which not only causes skin itching in patients, but also destroys the body environment through a series of pathophysiological processes, reduces the surgical tolerance of patients with resectable tumors, and affects the prognosis. Preoperative jaundice reduction can reduce jaundice and relieve biliary obstruction, but the various complications that follow will also adversely affect the treatment. This article elaborates on the disadvantages of different methods for jaundice reduction, the indications for preoperative jaundice reduction, the jaundice reduction options for different types of extrahepatic cholangiocarcinoma, the complications and treatment methods of preoperative jaundice reduction for extrahepatic cholangiocarcinoma, aiming to provide a reference for clinicians, so that patients can better benefit from preoperative jaundice reduction.
Objective To assess the changes of cardiac autonomic nerves’s function in patients underwent bronchofiberscopy by observing the dynamic electrocardiogram ( DCG) and heart rate variability ( HRV) , and investigate the effect of different preoperative medications on heart function.Methods Eighty patients underwent bronchofiberscopy were randomly divided into three groups according to different anaesthesia. Group A ( n =30) were local anaesthetized by nebulized lidocaine, group B ( n = 30) received atropine 1 mg injection intramuscularly and nebulized lidocaine, group C ( n = 20) were anaesthetized bypropofol intravenously. The DCG and HRV of three groups were mornitored at pre-inductive point( T0 ) , post inductive point ( T1 ) , point during the operation ( T2 ) , and point after operation ( T3 ) .Results The incidences of ST-T change, tachycardia, and bearing premature in group A and B were increased. The incidence of tachycardia in group C was also increased, but lower than group A and B while the ST-T change and bearing premature were milder ( P lt;0. 05) . Episodes of bradycardia occurred 3 times in group A andnone in group B and C ( P lt;0. 01) . The low-frequency ( LF) , high-frequency ( HF) , total power ( TP) in group A and B were raised, but the LF was highly raised, and the LF/HF and HRV significantly decreased.The LF/HF and HRV decreased lightly in group C ( P gt; 0. 05) . Conclusions Bronchofiberscopy examination can decrease HRV and induce arrhythmia and ST-T change, but also excite vagus nerve. Atropine can inhibit the excitability of vagus nerve and have no influence on HRV. The propofol may obviously decrease the sympathetic nervous activation, balance sympathetic and vagus nerves, which is beneficial to the stability of hemodynamics.
Objective To evaluate the accuracy of preoperative 64 multidetector spiral computed tomography (MDCT) in the diagnosis of stage Ⅳ gastric cancer. Methods The data of patients with stage Ⅳ gastric cancer between July 2007 and April 2008 were collected. Twenty-nine patients underwent preoperative 64 MDCT were retrospectively analyzed. All computed tomography scans were prospectly analyzed by 2 abdominal radiologists separately. Pathological tumor stage was based on TNM stage according to the revised Japanese Classification of Gastric Carcinoma from the Japanese Gastric Cancer Association. All CT results were compared with clinical, surgical and histopathologic results. Results The 65.2% (15/23), 47.8% (11/23) and 70.8% (17/24) of the stage Ⅳ patients were accurately predicted of T, N and M stage, respectively. Moreover, 58.6% (17/29) of the stage Ⅳ patients were accurately predicted of TNM stage. But 6/9 cases with peritoneal metastases were not detected by preoperative 64 MDCT. Conclusion The 64 MDCT is a promising technique for detection and preoperative staging of stage Ⅳ gastric cancer. It was difficult to detect peritoneal metastases, but it may not increase the rate of exploratory laparotomy.
Objective To evaluate the reliability and validity of the Chinese version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) in preoperative anxiety in patients with local anesthesia. Methods From May to December 2020, a convenient sampling method was used to conduct an APAIS questionnaire survey on patients undergoing percutaneous renal biopsy in the Department of Nephrology, West China Hospital, Sichuan University, and the reliability and validity of the scale were analyzed. ResultsA total of 460 questionnaires were distributed and 444 valid questionnaires were returned, with a valid response rate of 96.5%. The Cronbach α of APAIS was 0.896, the Guttman split-half reliability was 0.811, and the content validity index was 0.891. The model fit was 12.122 for the chi-square fit index/degree of freedom, 0.916 for the goodness-of-fit index, 0.902 for the value-added fit index, 0.079 for the root mean square error of approximation, and 0.946 for the comparative fit index. The APAIS anxiety subscale score was positively correlated with the 7-item Generalized Anxiety Disorder Scale score (r=0.518, P<0.001). Conclusion The APAIS has good reliability and validity for evaluating the level of preoperative anxiety in patients with local anesthesia, but the application of the scale in other conditions requires further testing.
Atrial fibrillation is one of the most common complications after coronary artery bypass grafting (CABG), with the occurrence rate of approximate 30%, which leads to hemodynamic instability, reduces survival rate, prolongs hospitalization, and increases patients' economic burden. Previous numerous studies have shown lots of preoperative, intra-operative and postoperative factors can predict the occurrence of new onset atrial fibrillation after CABG. If we can identify the specific patients at high risk for developing atrial fibrillation before operation, we may prevent atrial fibrillation more effectively, avoiding unnecessary prophylactic treatment and its risk. This review only focuses on research progress of preoperative predictors.
