This article analyzes mainly the X-ray imaging acquisition parameters in AXIOM Artis X-ray equipment, the relationship between the parameters, and how to select acquisition parameters in cardioangiography. We have sought a set of X-ray imaging acquisition parameters for producing optimal image in cardioangiography.

Objective To investigate the clinical efficacy,indications and complications of transcatheter arterial embolization for the treatment of traumatic hemorrhage of liver.Methods Retrospectively analyzed 33 cases of traumatic hemorrhage of liver admitted to West China Hospital from May 1996 to May 2006.Twenty-four cases underwent hepatic arterial angiography and were diagnosed as hepatic arterial pseudoaneurysms and followed by superselective embolization of the feeding vessel with gelatin sponge and/or spring coils.Results Embolization was succeeded technically in 28 pseudoaneurysms of 24 cases.Rebleeding occurred in 2 cases and a second embolization was performed with one recovered uneventfully.The other died of rebleeding and severe abdominal infection one week after the second embolization.Fever unrelated to embolization occurred in 9 cases.Conclusion Transcatheter arterial embolization is safe,prompt and effective for the treatment of hemorrhage due to hepatic injury.(J Intervent Radiol,2007,16:226-228)

Objective To study the methods and value of emergency interventional therapy in digestive tract bleeding.Methods 61 cases with digestive tract bleeding accepted emergency angiography.According to find out positions and causes of bleeding during angiography,these patients accepted arterial embolization and /or perfusion of vasoconstrictor substance.Results In 29 cases accepted arterial embolization and 32 cases accepted perfusion of vasoconstrictor substance,the stoped bleeding immediately occured in 100% and 82.7% respectively.Bleeding recurrence was 3 cases in the patients with arterial embolization one week later and 25 cases of the patients with perfusion of vasoconstrictor substance forty-eight hours later.Conclusion To treat the digestive tract bleeding by arterial embolization or vasoconstrictor substance perfusion are safe and effective hemostatic ways during emergency angiography.Though the bleeding recurrent rate is high after vasoconstrictor substance perfusion,these ways can race against time for surgical operation.

BACKGROUNDTo investigate the indication, complication and efficacy of bronchial artery embolization for the management of lung cancer with massive hemoptysis.

METHODSThirty-eight cases of lung cancer with massive hemoptysis were retrospectively analyzed in our hospital from January 1996 to January 2003. All cases presented with acute hemoptysis from 220 to 980 ml daily, with a mean of 290 ml daily. A digital subtracted bronchial arteriogram was perfomed and bleeding arteries were embolized.

RESULTSHemoptysis decreased gradually in all cases and ceased in 3 or 4 days after embolization. Recurrence was found only in one case 2 months after embolization and second embolization was applied to control hemoptysis. No serious complications occured.

CONCLUSIONSBronchial artery embolization is safe and efficient for the management of lung cancer with massive hemoptysis.

Objective:To deeply understand the reason and inner experience of day surgery patients canceling surgery through qualitative research, so as to strengthen the management of day surgery patients.Methods:This research adopted phenomenological research method. From June to December 2019, purpose sampling was used to select 12 patients who had canceled the day surgery at Ningbo First Hospital in Zhejiang Province for a semi-structured interview. The Colaizzi 7-step analysis method was used for data analysis.Results:Through repeated refining, analysis and extraction of interview data, the reasons and inner experience of day surgery patients who canceled surgery were finally summarized into 5 themes. Those themes included fear of day surgery, distrust of day doctors, affected by basic diseases and physiological factors, lack of confidence in community medical care, insufficient preparation before surgery.Conclusions:The reasons for day surgery patients to cancel surgery include fear of surgery, distrust of doctors, basic diseases and physiological factors, lack of confidence in community medical care, and insufficient preparation before surgery. It is recommended that day surgery medical and nursing staff strengthen day ward management, improve their professional level and ability to communicate with patients, and at the same time promote the construction of hospital-community integration to ensure the medical safety of patients after discharge from the hospital, and further reduce the cancellation rate of day surgery.

Objective? To explore the application effects of bundle care strategy to enhanced recovery after surgery (ERAS) based on evidence-based nursing practice for patients with gastric cancer during perioperative period. Methods? From July 2017 to June 2018, a total of 100 patients undergoing radical gastrectomy in Ningbo First Hospital were selected and divided into control group and observation group according to admission time, with 50 cases in each group. The control group received routine enhanced recovery nursing based on guidelines. Bundles of care was determined and implemented in the observation group based on the embodiment of ERAS after literature review combined with expert consultation. The first anal exhaust time, defecation time, ambulation time, hospitalization days, ADL score on the third day after operation, pain score at 24 and 48 hours after operation, and complications of infection were compared between the two groups. Results? The first anal exhaust time, defecation time and ambulation time of the observation group were 66 (53,78) h, 88 (76,100) h and 29 (24,36) h, which were all lower than those of the control group [72 (60,90) h, 96 (82,120) h and 36 (24,48) h], and the differences were statistically significant (P＜0.05). The ADL score on the third day after operation was (65.88±14.37), which was higher than that of the control group (59.18±14.31), and the difference was statistically significant (P＜0.05). The hospitalization duration of the observation group was 11 (10,12) days, which was shorter than that of the control group 12 (11,13) days, and the difference was statistically significant (P＜0.05). There was no statistical significance in the difference in the pain score at 24 and 48 hours after operation and the complications of infection between the two groups (P＞0.05). Conclusions? Bundle care strategy of enhanced recovery after surgery for patients with gastric cancer can promote postoperative gastrointestinal function recovery, improve postoperative self-care ability and shorten postoperative hospital stay.

Objective:To explore the application effect of evidence-based clinical practice of enhanced recovery after surgery multiple discrepancies theory (ERAS-MDT) in perioperative nursing of patients with hepatectomy.Methods:From January to December 2018, 62 patients with hepatectomy who received perioperative care of ERAS-MDT in the Department of Hepatobiliary and Pancreatic Surgery of Ningbo First Hospital of Zhejiang Province were selected as the control group. We reviewed the implementation effect, searched the clinical practice guidelines, systematic reviews and evidence summary related to ERAS-MDT, carried out field investigation and expert consultation, summarized the obstacle factors, formulated countermeasures, and built a standardized operation mode of ERAS-MDT. From January to December 2019, a total of 66 patients with hepatectomy who received standardized ERAS-MDT perioperative nursing were selected as the observation group. The first exhaust time, defecation time, first ambulation time, first oral feeding time, hospitalization time, nutritional status and pain score were compared between the two groups.Results:The first exhaust time, defecation time, first ambulation time, first oral feeding time, hospitalization time of the observation group were earlier than those of the control group, and the differences were statistically significant ( P<0.05) . The albumin level of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.05) . The pain scores of the observation group on the operation day was lower than those of the control group, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:A standardized management model of ERSA-MDT based on evidence-based clinical practice exhibits positive effect on the perioperative recovery of hepatectomy patients, which can further improve the clinical outcome of patients.
