A symposium on Total Intravenous Anaesthesia (TIVA) was organised by the Department of Anaesthesia and Intensive Care, PGIMER on June 11, 2016 under the chairmanship of Prof GD Puri, Head, Department of Anaesthesia in the Lecture Theatre Complex, Nehru Block, PGIMER. Prof S Palvannan , Visiting Professor to PGIMER from Brisbane, Australia, Prof Promila Chari ex-head of Anaesthesia department at PGIMER, Dr Jayshree Sood, Head of Anaesthesia at Sir Ganga Ram Hospital, New Delhi, Prof YK Batra, Anaesthesia head at Max Hospital Mohali and Prof S Gombar, Head of anaesthesia department, GMCH 32 were among the renowned faculty members from India and abroad who participated in the one day symposium. The Symposium was attended by more than 100 postgraduate anaesthesia students.
Conventionally anaesthesia is provided using inhalational agents or gases in combination with other intravenous drugs for anaesthetising the patient. The use of nitrous oxide and other inhalational agents has been reported to cause green house effect and result in vitamin B12 deficiency in the patients being exposed to them. Advanced cardiac centre is the lone hospital in the country which is nitrous oxide free. Advanced cardiac centre is the lone hospital in the country which is nitrous oxide free. The current awareness about the environmental hazards and problems faced by the operation theatre personnel with these inhalational agents, has shifted the trend towards total intravenous anaesthesia. Total intravenous anaesthesia involves the use of shorter acting intravenous anaesthetic agents like propofol in combination with the opioids. This symposium was meant to update the participants about the recent developments in the field of total intravenous anaesthesia.
There were lectures on the benefits of TIVA for Operation theatre personnel and the future prospects of TIVA in anaesthesia. The second session had lectures on the use of TIVA in children, in weight reduction surgery for obese patients, open cardiac surgery and liver transplant surgery. Providing anaesthesia at higher altitudes is also a challenge for the anaesthetists and this was highlighted in the lecture on TIVA at higher altitudes. This was followed by an interesting debate on the use of TIVA in lung and thoracic surgery which involves ventilation of only one lung and nitrous free anaesthesia. The highlight of the Symposium was the introduction to the Closed Loop Anaesthesia Delivery System (CLADS) which involves automatic computer controlled intravenous anaesthetic drug delivery according to the requirement of the patient by monitoring the depth of anaesthesia. The experience of this system in different set of anaesthesia was presented.
