Introduction: Operating time is interval between the instant of the occurrence of specified input condition to system and the instant of completion of a specified operation. Operations carried out for the correction of deformities and defects, repair of injuries and diagnosis and cure of certain diseases. Controversy exists concerning the importance of operative time on patient outcomes. Objective: The aim of this study was to identify the impact of operative time on outcome in laparoscopic surgery. Methods: Purposive sampling method was applied to get desired number of samples. A total number of 61 cases were enrolled in this study. Data were collected in a pre-designed data collection sheet from the records of laparoscopic surgery cases of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh after taking permission from the authority. Patients who underwent laparoscopic general surgery procedures (colectomy, cholecystectomy, Nissen fundoplication and inguinal hernia. from the 2017–2019 participant use file were identified. Results: A total of 61 elective general surgical patients who underwent laparoscopic procedures were analyzed. Univariate analyses of deciles of operative time demonstrated a statistically significant trend toward increasing odds of complications with increasing operative time for laparoscopic colectomy (n=10), cholecystectomy (n=32), Nissen fundoplication (n=4), and laparoscopic inguinal hernia repairs (n=15). Multivariate modeling revealed the effect of operative time to remain significant after controlling for additional patient factors. Conclusion: Increasing operative time was associated with increased odds of complications and, therefore, it appears that speed may matter in laparoscopic surgery.

The general objective of this study was to evaluate the action of Naja nigricollis venom on certain biochemical parameters of rabbits. To carry out this study, three batches of three rabbits were formed with two control batches and one experimental batch. Each control lot is composed of three rabbits (male or female) while the experimental lot is composed of two males and one female. Each rabbit from the control lots was collected separately from the red tube (dry tube) and transported to the laboratory for analysis. The rabbits from the experimental batch were also collected separately a few minutes after the injection of Naja nigricollis venom for analysis of biochemical parameters. However, prior to these experiments, an in vitro hemolysis test of Naja nigricollis venom was performed on whole blood to verify the hemolysing power of Naja nigricollis venom. The results of this study reveal that:- the venom of Naja nigricollis has a dose-dependent hemolysing power in vitro and in vivo;- with a few exceptions, the biochemical parameters of males are generally higher than those of females;- the venom of Naja nigricollis causes kidney failure and cardiovascular disease in some animals, promotes a risk of coronary death and diabetes in others, causes neuromuscular and cardiac signs due to dyskalemia in others, and finally, a hepatocellular damage or disturbance of bile flow, a heart problem and vitamin B6 deficiency in one type of animal. - the venom of Naja nigricollis is fatal.

Palpebral ptosis is the dropping of the upper eyelid and is one of the most common oculoplastic problems. This anomalous position of the eyelid is usually caused by a dysfunction of the lifting muscle, and can affect both adults and children. In the most serious cases, it can affect the visual axis by blocking the pupil and limiting or even totally preventing vision. The surgery treatment of palpebral ptosis is usually frontalis suspension allows to improve the vision field by raising the eyelid again while improving the physical appearance of the affected person by improving the look. We conducted a retrospective study on the anatomical and functional results of ptosis surgery using a silicone probe in 18 patients operated on in our establishment. The aim of this work was to evaluate the anatomical and functional results of the use of silicone probes in the frontal suspension and to highlight the advantages of silicone in this indication.
