Comparison of different methods of general anaesthesia for controlled hypotension in functional endoscopic sinus surgery (FESS)
Journal Title: Indian Journal of Clinical Anaesthesia - Year 2018, Vol 5, Issue 4
Abstract
Introduction and Aims Functional Endoscopic Sinus Surgery FESS is minimal invasive technique for management of chronic sinusitis Controlled hypotension is required in FESS for bloodless field better visualization reduce operative time and bleeding Various agents like blockers blockers magnesium sulfate etc used to achieve controlled hypotension The aim of study was to produce controlled hypotension with propofol and isoflurane and to compare intraoperative blood loss duration of surgery operative field conditionMaterials and Methods Sixty patients were assigned in either group by computer generated random number table Patients in Group A received propofol infusion and in group B received isoflurane in concentration to achieve MBP between 60 to 70 mmHg Bispectral index value was also maintained between 40 to 60 Statistical difference between two groups was determined using unpaired student t test except for surgical field condition for which Median test for two populations was used A p value Result There was no statistically significant difference in MBP between both groups Mean intraoperative blood loss was less in group A 115171207 ml compared to group B 14051583 ml Mean duration of surgery was shorter in group A 109932 min compared to group B 131671282 min Operative field condition was better in Group A compared to Group B p00026Conclusion Both propofol and isoflurane effective in producing controlled hypotension but anaesthesia with propofol is associated with less blood loss shorter duration of surgery and better surgical field condition compared to isofluraneKeywords Bispectral Index Controlled hypotension Functional endoscopic sinus surgery Isoflurane Propofol

Study of spinal anaesthesia with isobaric levobupivacaine and ropivacaine in elective lower limb orthopaedic surgeries
Introduction and Objectives: Levobupivacaine and Ropivacaine, the two S enantiomers of Bupivacaine can be safer alternatives to racemic bupivacaine due to claims of cardiovascular safety profile. Hence, this study was co...

Introduction: Ropivacaine is the single enantiomer specific local anaesthetic having reduced potential for cardiotoxicity and neurotoxicity. Its characteristics of slow onset, shorter duration of sensory analgesia and ra...
A study to evaluate the effectiveness of Bupivacaine (0.5%) versus Ropivacaine (0.5%, 0.75%) in patients undergoing upper limb surgery under brachial plexus block
Introduction: Brachial plexus block is the commonest form of regional anaesthesia being used for upper limb surgeries. Bupivacaine is most widely used local anaesthetic in regional anaesthesia, but its cardiotoxicity has...
