We conclude that co-induction with remifentanil alone or with midazolam can be used to reduce propofol doses at induction of anaesthesia using target-controlled infusions. We believe that using effect site concentration may prove a useful tool in routine clinical practice.
Background: Successful insertion of Laryngeal Mask Airway (LMA) requires sufficient depth of anesthesia and depression of airway reflexes to avoid gagging, coughing and laryngeal spasm. The LMA is popular because it is easy to insert and it provides a secure airway for the patients who breathe spontaneously. Indeed, the intravent LMA instruction manual specifically recommends propofol for induction of anesthesia during LMA insertion. As a matter of fact Propofol and LMA insertion has become synonymous. However, there are some problems related to the use of propofol, for example, relatively high cost. This observational study was conducted to compare efficacy and safety of propofol and thiopentone -midazolam in smooth insertion of LMA and the hemodynamic changes over time in both groups.
Methods: The study was done in the Department of Anesthesiology, Chittagong Medical College from July, 2012 to December, 2013. All the patients scheduled for elective surgical procedures under general anesthesia fulfilling the inclusion criteria, were the study population. Data was analyzed by computer based software SPSS-21. Results: Overall LMA insertion condition was improved better by the use of midazolam with thiopentone sodium (Group B) than propofol (Group A). The drug regime used in group A (Propofol) was expensive than group B (midazolam with thiopentone sodium) with indifferent hemodynamic stability in both groups. Mean ages of patients were 32.43 years ± SD- 10.67 years in group A and 33.5 years ± SD- 10.63 years in group B.
Conclusion: In the perspective of our study, for smooth insertion of LMA midazolam-thiopentone sodium regime is cheaper and can be effectively and safely used over propofol regime.

Background: Adding narcotics to local anesthetic is very effective in prolonging the analgesic effects. The aim of this study is to evaluation the efficacy and safety of fentanyl as an adjuvant with bupivacaine-lignocaine in supraclavicular block.
Methods: This analytical study was carried out in the department of anesthesiology in Chittagong Medical College Hospital in collaboration with the department of orthopedic surgery over a period of 22 months starting from January 2012 to December 2014. A total 130 adult patients of either sex with American Society of Anesthesiology (ASA) health status I-II were selected for upper limb surgery under supraclavicular brachial plexus block was randomly allocated in to two groups of 65 patients in each. Group- C was received Distilled water 2ml and Group-F was received fentanyl 2ml (100 g) in 38ml of bupivacaine and lignocaine with adrenaline (Total volume of 40ml).
Results: The mean onset of sensory & motor block was 10.49±0.75 min & 9.41±0.76 min in group-C and 7.60±3.711min & 9.23±5.114min in group-F. The duration of analgesia in group-C was 3.81±0.88 hrs and in group-F was 8.62±1.747 hrs.
Conclusion: There was significantly prolonged duration of analgesia and better onset of sensory and motor block in fentanyl group without any unwanted effects.
