RESUMO
The Impella is a left ventricular assist device which is implanted via the transcutaneous femoral route and is placed across the aortic valve into the left ventricle. We report an interesting case where cardiopulmonary resuscitation was associated with displacement of Impella device. Impella is being increasingly used these days especially in patients with cardiogenic shock. Clinicians should have high index of suspicion for displacement of Impella in appropriate clinical setting

Propofol is a commonly used short-acting intravenous anaesthetic agent. A major disadvantage of propofol is pain at injection site with high incidence up to 90%. Various modalities have been tried to obtund propofol-induced pain; however, search for an ideal agent continues. We assessed the effect of double and triple dilution of 1% propofol emulsion with normal saline on pain at injection site. This randomized, double-blinded study was done on 60 adult patients of both sexes, belonging to ASA grade I and II scheduled for elective surgery under general anesthesia, divided into three groups named I, II, III of 20 patients each. The patients of group I, II, and III received 1% propofol 2 ml, 0.5% propofol 4 ml, and 0.33% propofol 6 ml, respectively, over a period of 4 s and pain felt was assessed. There was no statistically significant difference in the pain score in group II as compared to patients in group I. However, there was a statistically significant decrease in the pain score in group III as compared to patients in group I [P value 0.02] and group II [P value 0.03]. Conclusions: We found a significant decrease in both incidence and severity of pain during injection with a 0.33% propofol solution without significant adverse hemodynamic effects. The small size of data was a limitation in our study and a large-scale study will be needed to prove its therapeutic beneficence
