Case of Liver Metastasis for RFA

Radiofrequency ablation (RFA) for liver metastasis is a minimally invasive technique to treat primary or metastatic cancer lesions. Most of the times, RFA is conducted in out of operating room settings, in a specialised radiology suite. Lack of favourable surroundings and unavailability of proper equipment along with lack of trained staff are challenges of anaesthesia practice in non-operating room anaesthesia. Patient posted for RFA are frail and have multiple comorbidities with advanced cancer which further increases the challenges. Anaesthesia technique can vary from monitored anaesthesia care, with or without regional anaesthesia, to general anaesthesia. Periprocedural goals are to keep patient immobile along with adequate pain control. Pain is an important concern as it is due to combined effect of, skin puncture along with thermal ablation of tumour tissue. The choice of anaesthesia depends on site, size of tumour along with patient profile and radiologist experience. Adequate peri procedure monitoring is an essential component of anaesthesia practise. Post procedure, patient should be monitored for at least 30 min for any adverse effects.
