A case of organophosphate (OP) poisoning who recovered after requiring almost 1000 mg of atropine, 10 gm of PAM and ventilatory support for 7 days is presented here. The overview of organophosphate poisoning and its management is given. With the approach adopted, the mortality reported in the general medicine unit in the central hospital in Nepal is 7.4%. The two important aspects of the management are vigilance of the atropine drip, especially at night, and other physical and psychological support care of the patients.  相似文献

Pre-operative counselling is an important part of the care that we give to our patients undergoing surgery. It ensures that the patients understand about their disease and the procedure that they are undergoing. This study was done with the objective of finding whether or not the patients do actually understand what has been explained to them. This is a prospective study done in the form of a survey with a set questionnaire in two hospitals in Kathmandu namely Patan hospital and Tribhuvan University Teaching Hospital. The patients surveyed were those who were admitted for elective surgery after counselling has been done and consent forms signed. The result showed that the level of understanding was poor in 11%, unsatisfactory in 33%, satisfactory in 37% and excellent in 19%. The level of understanding was affected by the education level of the patients. To conclude, the level of understanding was unsatisfactory in nearly half the patients. Only 19% had optimal understanding. This may reflect the education level of the many of our patients but it clearly points out that the medical profession needs to make more effort to make the patients understand more about their disease process. This can be said to be a reflection of our quality of care.  相似文献

Cationic computed tomography contrast agents are more sensitive for detecting cartilage degeneration than anionic or non-ionic agents. However, osteoarthritis-related loss of proteoglycans and increase in water content contrarily affect the diffusion of cationic contrast agents, limiting their sensitivity. The quantitative dual-energy computed tomography technique allows the simultaneous determination of the partitions of iodine-based cationic (CA4+) and gadolinium-based non-ionic (gadoteridol) agents in cartilage at diffusion equilibrium. Normalizing the cationic agent partition at diffusion equilibrium with that of the non-ionic agent improves diagnostic sensitivity. We hypothesize that this sensitivity improvement is also prominent during early diffusion time points and that the technique is applicable during contrast agent diffusion. To investigate the validity of this hypothesis, osteochondral plugs (d = 8 mm, N = 33), extracted from human cadaver (n = 4) knee joints, were immersed in a contrast agent bath (a mixture of CA4+ and gadoteridol) and imaged using the technique at multiple time points until diffusion equilibrium. Biomechanical testing and histological analysis were conducted for reference. Quantitative dual-energy computed tomography technique enabled earlier determination of cartilage proteoglycan content over single contrast. The correlation coefficient between human articular cartilage proteoglycan content and CA4+ partition increased with the contrast agent diffusion time. Gadoteridol normalized CA4+ partition correlated significantly (P < .05) with Mankin score at all time points and with proteoglycan content after 4 hours. The technique is applicable during diffusion, and normalization with gadoteridol partition improves the sensitivity of the CA4+ contrast agent.  相似文献
