BackgroundReal-time ultrasound (US) in central venous catheterization is superior to pre-procedure US. However, ensuring real-time US into routine practice is impeded by its perceived expense and difficulty. This expertise requires hand–eye coordination and learning curve. Moreover, availability of multiple US machines and probes for multiple operation theatres may not be possible even at the tertiary level care set-up. Currently, pre-procedure US and landmark methods are most widely used. We investigated both the techniques with application of skin markings in the pre-procedure group to ascertain efficacy and safety with a view to incorporate pre-procedure US in our practice.MethodsIn this randomized study, we investigated 66 patients. Thirty-three patients in the pre-procedure ultrasound group and 33 patients in the landmark group were included for right internal jugular vein (RIJV) cannulation. We recorded the first needle pass success rate, cannulation time and complications.ResultsPre-procedure US was associated with more successful attempts, shorter cannulation times and less complications. Under pre-procedure US, 75.76% of first attempts were successful with a cannulation time of 50 (25–180) seconds. Under landmark technique, 27.27% of first attempts were successful with a cannulation time of 85 (20–200) seconds. First puncture success rates were higher in pre-procedure US than landmark technique, 66.67% vs 27.27%, respectively.ConclusionPre-procedure US for RIJV catheterization is safer, quicker and superior to landmark technique. 相似文献

Objectives:To experimentally evaluate the effects of preoperative fasting duration on distant organ liver in renal ischaemia-reperfusion (IR) injury.Methods:This is an experimental study. In the study, 3 groups were formed. In Group A, abdominal laparotomy was carried out after 12 hours of preoperative fasting without any IR damage. In Group B, IR injury was carried out after 12 hours of preoperative fasting, and abdominal laparotomy was carried out, in Group C after 2 hours of fasting after IR injury. Apoptosis, congestion, balloon degeneration, nuclear pleomorphism, and leukocyte infiltration were examined histopathologically and tumor necrosis factor-alpha (TNF-α), interleukin (IL) -1 beta, IL-6, and IL-10 were evaluated biochemically.Results:A statistically significant difference was determined between the groups in respect of postoperative IL-10 levels (p=0.020) with significantly lower levels determined in Group C than in Groups A and B (p=0.021). Similar rates of mild nuclear polymorphism were seen with no statistically significant difference determined between the groups (p>0.167). A statistically significant difference was determined between the groups in respect of the congestion scores (p<0.001), with a lower score in Group C than in Groups A and B, where the scores were similar (p<0.001, p=0.017).Conclusion:With this result, it would be correct to say that the short preoperative fasting period has protective effects on the liver tissue. 相似文献

The extraordinary events surrounding the measles, mumps, and rubella (MMR) vaccine in the United Kingdom have not only placed in jeopardy the use of this triple vaccine but have also spread concern to other parts of the world. Examination of the public's worry about MMR vaccine reveals they have been exposed to a range of conflicting views resulting in the feeling of having been misled about the safety of the vaccine. There are various groups and individuals who have legitimate roles in informing the public about such subjects. But is each one behaving in an ethically responsible way? And if confidence falters, vaccine coverage dips, and an outbreak of measles, mumps, or rubella ensues, who, if anyone, will stand and say "I misled them, I confused them, this is my responsibility"? We examine the ethical issues of each group with a voice in the debate about vaccine safety. 相似文献

Objectives: Formal efforts to improve patient education are associated with fewer disease complications in a number of conditions. The possible relationship between knowledge about ulcerative colitis and its cancer risk, and the development of colorectal cancer using a previously developed and validated instrument—the Crohn''s and colitis knowledge (CCKNOW) score—were investigated. Methods: The 24 item CCKNOW questionnaire was mailed to patients known to have developed colorectal cancer as a complication of ulcerative colitis (cases) and to colitics from the Leicestershire inflammatory bowel disease patient database who had not developed cancer (controls). Results: The mean (SD) CCKNOW scores for cases was 8.21 (3.02) and for controls was 8.27 (4.3). These scores did not differ significantly between cases and controls (difference 0.06, 95% confidence interval (CI) -1.7 to 1.5, p=0.9). There were four times as many members of the National Association of Crohn''s and Colitis (NACC) in the control group compared with the cancer group and patients who are members of NACC achieve statistically significantly higher scores than non-members (11.6 v 7.8, p=0.05, 95% CI -0.1 to 7.6). However, after adjusting for NACC membership, the CCKNOW score did not appear to be associated with having developed cancer (odds ratio 1.04, 95% CI 0.92 to 1.18, p=0.5). Conclusions: The CCKNOW scores were comparable in cases and controls. Thus, in a retrospective study, no evidence has been demonstrated of an association between patient knowledge and the risk of developing colorectal cancer in patients with ulcerative colitis. However, knowledge may have been increased in cases as a direct result of having had colorectal cancer as a complication of ulcerative colitis. 相似文献

Objectives:To compare the digital radiology rejection rates and reasoning pre-COVID-19 (PC) and during COVID-19 (DC) from September 2019 to August 2020.Methods:This record-base retrospective study where data were extracted from the radiography equipment (Carestream Health, Rochester, New York, USA) at the Department of Radiology, King Abdulaziz University Hospital, Jeddah, Saudi Arabia over 12 months. The data were equally divided into PC and DC.Results:The DC rejection rate decreased from PC by 2.6% with a significant p=0.00001. During COVID-19 there were 15,376 images of different body parts, versus 23,861 images during PC. Position errors were the main reasons for rejection for both PC (39.8%) and DC (42.7%), followed by technique errors (PC: 19.2%) (DC: 17.2%).Conclusion:Different sectors in hospitals were affected by COVID-19, including diagnostic radiology, in the positive direction. Thus, the DC rejection rate was markedly reduced compared with PC. This may be due to radiology technicians becoming more cautious in dealing with patients. 相似文献

A case-control study was carried out in Alor Gajah to determine the socio-economic, dietary and lifestyle factors and the occurrence of pregnancy-induced hypertension. There were a total of 30 cases who were selected from antenatal mothers attending 3 selected health centers in 1998. The control group consisted of 30 antenatal mothers who were matched according to health centre, race and age. The results showed that pregnancy-induced hypertension was significantly associated with obesity (P < 0.05) and being a housewife (P < 0.05). 相似文献

Objectives:To determine the influence of coronavirus disease-19 (COVID-19) on cochlear tasks of children who had COVID-19 previously, and the relevance among disease seriousness and cochlear involvement by otoacoustic emissions (OAEs).Methods:The study included 24 hospitalized children after COVID-19 diagnosis, 23 pediatrics that received outpatient treatment, and 21 children who were without COVID-19 diagnosis as the control group between June 2021 and July 2021. Transient evoked otoacoustic emission (TEOAE), distortion product otoacoustic emission, and contrlateral suppression of otoacoustic emission measurements were carried out for each child. Symptoms of patients, the treatments they received, and the duration of hospitalization of the children in the hospitalized group were recorded.Results:The comparison of TEOAE test results under masking showed a considerable difference between 3 groups at 1 kHz (p=0.033) and 4 kHz (p=0.021) frequencies (p<0.05). Distortion product otoacoustic emission test results of hospitalized outpatient and control group showed a statistically significant difference at 2 kHz among themselves (p=0.009).Conclusion:Our results suggest that severe acute respiratory syndrome coronavirus-2 may influence the medial olivocochlear system of children and have irreversible effects on the cochlear functions. Early detection of problems that may affect cochlear functions is a special critical task, especially in children, who are a particularly vulnerable group in terms of hearing and related speech problems. 相似文献
