Background:Pain in the perioperative setting or thereafter plays a significant role in delaying an otherwise successful recovery. Hence, mitigation of such postoperative pain assumes importance. Among the various agents employed for such mitigation, opioids and non-steroidal anti-inflammatory drugs have for some time taken center stage. However, alas they are not without their share of adverse effects. This study was undertaken with the purpose of elucidating the efficacy of intravenous (IV) paracetamol as compared to IV tramadol in mitigating postoperative pain while observing its effect on hemodynamic stability and the presence of adverse drug reactions, if any.Materials and Methods:A total of 60 randomized cases aged ranges from 20 to 60 years of both sexes divided into two groups (each for paracetamol and tramadol) scheduled for laparotomies were administered IV paracetamol and tramadol for postoperative pain relief and assessed with visual analog scale (VAS) score and variations in vital parameters to ascertain extent of pain relief and post-operative nausea vomiting (PONV).Results:Data so collected was statistically interpreted, and observations extrapolated. Save for a perceptible decline in PONV with paracetamol group compared with tramadol group with a statistically significant P < 0.001, nothing statistically significant was observed in any other parameter, including VAS scores between either group.Conclusion:IV paracetamol is a safer alternative to tramadol with lesser PONV in the postoperative period translates into the lesser duration of hospitalization and hence earlier discharge.

BACKGROUND Central venous catheterisation is a vital intervention in critically ill patients. The proper route of insertion is essential for its success. Objective of this study is to compare procedural parameters and complications associated with anterior and posterior approaches of internal jugular venous cannulation. MATERIALS AND METHODS Our study was conducted as prospective randomised clinical trial in 100 patients posted for elective, emergency surgeries and critically ill patients in intensive care unit. Patients were randomly allocated into two groups of 50 patients each. Demographic data, number of attempts, procedural parameters and incidence of complications were compared in both groups. RESULTS Time for identifying the vein, number of attempts, duration for cannulation and incidence of complications like carotid puncture and haematoma were less in posterior approach when compared to anterior approach. CONCLUSION Posterior approach in internal jugular vein cannulation is safer and it has a better success rate as compared to anterior approach.

A bstract Background Central venous catheterization is a vital procedure for volume resuscitation, infusion of drugs, and for central venous pressure monitoring in the perioperative period and intensive care unit (ICU). It is associated with position-related complications like arrhythmia's, thrombosis, tamponade, etc. Several methods are used to calculate the catheter insertion depth so as to prevent these position-related complications. Objective To compare Peres’ formula and radiological landmark formula for central venous catheter insertion depth through right internal jugular vein (IJV) by the anterior approach. Materials and methods A total of 102 patients posted for elective cardiac surgery were selected and divided into two equal groups—Peres’ group (group P) and radiological landmark group (group R). Central venous catheterization of right IJV was done under ultrasound (USG) guidance. In group P, central venous catheter insertion depth was calculated as height (cm)/10. In group R, central venous catheter insertion depth was calculated by adding the distances from the puncture point to the right sternoclavicular joint and on chest X-ray the distance from the right sternoclavicular joint to carina. After insertion, the catheter tip position was confirmed using transesophageal echocardiography (TEE) in both the groups. Results About 49% of the catheters in group P and 74.5% in group R were positioned optimally as confirmed by TEE, which was statistically significant. No complications were observed in both the groups. Conclusion Radiological landmark formula is superior to Peres’ formula for measuring optimal depth of insertion of right internal jugular venous catheter.
