Radiofrequency waves are used to produce heat on specifically identified nerves generating heat around the nerve. Target nerve is confirmed after sensory and motor stimulation ,thus increasing the safety profile. The nerve is ablated, thus destroying its ability to transmit pain signals to the brain. Because of RFA's long-lasting results, the pain medication requirement is reduced. Nerve blocks with local anesthetics and long acting steroids provides results which lasts for short duration contrary to RFA which provides long lasting results ranging from 6 months to 2 years.
Procuring the machine through proper channel was a time consuming affair.
Familiarizing the pain fellows, post graduates to the nuances of RFA use was the next obstacle- This was overcome by proper demonstration after procuring the RFA machine
Sensitizing the OT personnel about gentle handling of the machine-This was achieved by conducting classes for OT technicians
Maintenance issues - any defect/ malfunction cannot be addressed immediately due to lack of technical support. In such circumstances the company personnel is approached through proper channel and sorted out.
There is a rise of liver disease among the current population especially middle aged patients, ending up in end stage liver disorders. These patients with increased morbidity and mortality require liver transplant for survival and better quality of life. Hence liver transplant program at an affordable cost and holistic perioperative care was started in our hospital. To perform liver transplant surgery safely & effectively, allowing the surgical team to perform the transplantation procedure, anaesthesia & anesthesiologist play a vital role starting from the evaluation of the patient and post operative care.
The objective of anaesthesia for a liver transplant is to provide a safe, pain-fee and controlled environment for the patient during the surgical procedure. It includes minimizing the surgical stress, optimizing hemodynamic stability and ensuring a smooth transition from the OR to the ICU and out of the ICU.
The practice of anesthesia for liver transplant involves a specialized and meticulous approach tailored to the unique challenges of the procedure. Anesthesia for liver transplant typically follows these steps:
Preoperative Assessment: Anaesthesiologists assess the patient's medical history, current health status, and any potential risks. They formulate an anesthesia plan based on this evaluation.
Preparation: Anesthesia equipment and drugs are prepared. Intravenous lines and monitoring devices are placed on the patient. Baseline vital signs are recorded.
Preparation: Induction: Anesthesia is induced using intravenous medications to ensure the patient becomes unconscious and pain-free. Intubation is performed to secure the airway, and the patient is mechanically ventilated.
Preparation: Maintenance: Anesthesia is maintained throughout the surgery. Anesthesiologists monitor the patient's vital signs continuously, adjust anesthesia levels as needed, and manage fluids, drugs, blood products and ventilation parameters.
Preparation: Intraoperative Challenges: Liver transplant surgeries can present challenges such as massive blood loss and hemodynamic instability. Anesthesia providers work closely with the surgical team to manage these challenges, administering blood products, vasoactive drugs, and other interventions as necessary.
Preparation: Postoperative Care: After the transplant is completed, anesthesia providers assist in the patient's transition from anesthesia to the recovery area. They continue monitoring vital signs, manage pain and nausea, and ensure a smooth recovery process.
Preparation: Pain Management: Anesthesia providers are responsible for postoperative pain management, often using a combination of medications to keep the patient comfortable while ensuring they remain alert and responsive.
Post-Anesthesia Care: In the post-anesthesia care unit (PACU), patients are monitored as they recover from anesthesia. Anesthesia providers assess the patient's condition, manage any emerging issues, and ensure a safe transition to the regular hospital ward.
Throughout this process, communication and coordination with the surgical team and intensivists are paramount. Anesthesia providers must be prepared to handle any emergencies, adjusting their techniques and medications as the surgery progresses to ensure the patient's safety and well-being.
Anesthesia for liver transplant surgeries presents several challenges due to the complexity and duration of the procedure, as well as the underlying health conditions of the patients. Some obstacles include:
Hemodynamic Instability: Liver transplant surgery often leads to significant changes in blood flow and pressure, requiring careful management to prevent complications.
Coagulopathy: Patients with liver disease may have impaired blood clotting, increasing the risk of bleeding during surgery. Anesthesia must address this issue to prevent excessive bleeding.
Electrolyte Imbalance: Liver dysfunction can disrupt electrolyte balance, which needs to be closely monitored and corrected during the surgery.
Hyperkalaemia: Elevated potassium levels are common in liver transplant patients and can lead to cardiac issues. Anesthesia must be tailored to manage potassium levels effectively.
Renal Dysfunction: Liver transplant patients often have impaired kidney function, necessitating careful administration of anesthesia drugs to prevent further kidney damage.
Post-Reperfusion Syndrome: After the new liver is implanted and blood flow is restored, there can be a sudden drop in blood pressure, posing a significant challenge to anesthesia management.
Respiratory Challenges: Liver transplant surgery can affect lung function due to various factors, including fluid shifts and changes in chest mechanics, requiring vigilant respiratory support.
Immunosuppression: Patients receive immunosuppressive drugs post-transplant, which can affect their response to anesthesia and increase susceptibility to infections.
Graft Rejection: Anesthesia management is crucial in preventing complications related to graft rejection, which can be exacerbated by the stress of surgery.
Prolonged Surgery Duration: Liver transplant surgeries are often lengthy, increasing the risk of complications such as deep vein thrombosis and pressure sores, which anesthesia must address.
It's important to note that advancements in medical techniques and anesthesia practices continue to improve outcomes for liver transplant patients, but these challenges highlight the complexity of the procedure.
Implementing effective anaesthesia during this transplant has significant impact like patient safety, surgical success, reduced complication, improved graft acceptance and function, faster recovery with a better long term outcomes.
JSS Skill & Simulation centre was set up in 2020 with the sole intention of creating better learning opportunities for students and faculties in medical profession.
The facilities in the skill & simulation lab can be extended to almost all the clinical departments where the students are taught the various skills and subsequently simulating the scenarios can enable them to understand better.
The skill based manikins are available where the faculty of each department will teach the designated students the particular type of skill as per the check list. This will be repeated till the students is assessed for that particular type of skill and reassessed in case the goal is not met. For eg. Bag mask ventilation to target to 1st year student attains the goal of attaining complete chest rise. The various advanced surgical simulators and endoscopy simulators will enable the faculty to repeatedly practice the technique and also to educate the post graduate and super specialty postgraduates about the advanced skill in these practices. The simulation manikins are very useful in teaching the students about the correct protocols of managing emergency situations. The principles of crisis resource management can be best simulated during such practice sessions.
The debriefing sessions will enable the students to follow a protocol, season out the various thought process. The non technical skills and communication skills can be best assessed and taught during these simulation scenarios.
Regular BLS & ACLS classes are conducted.
The post graduates being less in number to cater the services in OT, ICU & periphery are not able to dedicate time to attend classes in the skill & simulation centre.
Strategies
With the use of skill education the students are exposed to various skills at a very early part of medical education. The same skills are applied in clinical practice. The check list of each procedure is followed by each student so that the technique of each skill and its preparation is well understood by the student. The student is allowed to practice repeatedly till perfection is achieved and the assessment is done on these skills.
The simulated scenarios gives an exposure of managing the emergency and non emergency situations where the technical as well as non technical skills are taught and assessed.
Difficult Airway is a common finding in the present-day Anaesthesia practice. Anticipated difficult airway poses a great challenge to any anaesthesiologist but unanticipated difficult airway is even more challenging as it comes as a total surprise. Awake flexible scope intubation is a gold standard for anticipated difficult airway. Since we are a tertiary care centre handling difficult cases like polytrauma, cervical spine injury and faciomaxillary surgeries this practice of using Flexible Intubating Scope (FIS) is absolutely necessary.
To provide safe airway management to all the patients undergoing anaesthesia and surgery in JSS Hospital with minimal airway related complications. FIS being a video endoscope allows the students to appreciate realtime airway anatomy and aids in teaching and training of ug, pg and allied health sciences students.
Patients are evaluated prior to anaesthesia. If a difficult airway is diagnosed then awake flexible intubation is planned. The procedure is explained to the patient as patient cooperation is crucial for the success of the procedure. On the day of surgery patients airway is anaesthetised and flexible scope intubation is performed by the anaesthesiologist to secure the airway.
In case of a unanticipated difficult airway FIS is used as a rescue device.
Impact of initiation of this practice has been enormous. Previously anticipated difficult airway cases were being referred and unanticipated difficult airway cases landed up in complications when intubation was not possible with conventional laryngoscopy. Once the practice of Flexible scope intubation has been started, we have handled all the cases of difficult airway without any complications. It has also helped in teaching the students about the airway anatomy.
Peripheral nerve blocks for various surgical procedures were previously performed using landmark techniques or with the help of peripheral nerve stimulator. The failure rates were significant since it relied either on anatomical landmark (which were subject to variation) or subjective perception. This increased the rates of conversion to general anaesthesia, which resulted in increased OT turnover times & increased cost. Introducing USG in this scenario helped us overcome this problem.
Central venous cannulation also was performed using landmark technique and was a blind procedure, the success of which relied mainly on the experience of the personnel. Also, risk of complications were higher with blind technique. Using USG has made Central Venous Cannulation a safer procedure.
The USG machine is used as per need for Peripheral Nerve Block, difficult Central Neuraxial Blockade, Central Venous Cannulation, airway assessment & pain procedures. It is also utilized extensively in the perioperative period for Transthoracic Echocardiography, assessing preopearative gastric volume, post operative analgesia by means of truncal and fascial plane blocks.
