From the Guidelines
During a laparoscopic partial nephrectomy, if poor tidal volumes are noted while using the argon beam coagulator, the immediate next step is to stop using the argon beam coagulator and check for a gas embolism. The anesthesia team should be notified immediately to assess the patient's hemodynamic status and ventilation. The pneumoperitoneum should be released temporarily by desufflating the abdomen to reduce intra-abdominal pressure. The patient should be placed in the Trendelenburg position (head down) and left lateral decubitus position to trap any gas emboli in the right atrium and prevent it from entering the pulmonary circulation. This complication occurs because argon gas can enter the venous system through open vessels during coagulation, particularly in highly vascular organs like the kidney. The gas can then travel to the heart, causing decreased cardiac output and subsequent poor tidal volumes. If the patient's condition doesn't improve, consideration should be given to central venous catheter placement to aspirate gas from the right heart, and echocardiography may be needed to confirm the diagnosis of gas embolism, as suggested by guidelines for management of clinical T1 renal mass 1.
Some key points to consider in this scenario include:
- The importance of immediate action to address potential gas embolism
- The need for close collaboration with the anesthesia team to manage the patient's hemodynamic status and ventilation
- The use of specific positions to trap gas emboli and prevent further complications
- The potential need for additional interventions, such as central venous catheter placement or echocardiography, to manage the patient's condition. However, it is essential to prioritize the patient's safety and well-being, and to take a cautious approach in the face of potential complications, as emphasized in the guidelines for management of clinical T1 renal mass 1.
In terms of the evidence, the guidelines for management of clinical T1 renal mass 1 provide a framework for approaching this scenario, and highlight the importance of careful consideration of the patient's individual needs and circumstances. The use of argon beam coagulator during laparoscopic partial nephrectomy is not explicitly addressed in the provided evidence, but the general principles of managing potential complications and prioritizing patient safety are relevant to this scenario. Overall, the key takeaway is the need for immediate and careful management of potential gas embolism during laparoscopic partial nephrectomy, with a focus on prioritizing the patient's safety and well-being.

Next Steps in Laparoscopic Partial Nephrectomy
During a laparoscopic partial nephrectomy, if poor tissue volumes are noted while using the argon beam coagulator, the next steps could involve:
- Adjusting the argon beam coagulator settings or technique to improve tissue coagulation and hemostasis 2
- Using additional hemostatic agents or methods, such as concentrated human albumin with argon-beam coagulation, to control hemorrhaging and urinary leakage 3
- Applying fibrin tissue sealant to the transected partial nephrectomy bed to achieve strict hemostasis and prevent urinary extravasation 4
- Employing other excisional techniques, such as the Harmonic Scalpel, in conjunction with the argon beam coagulator to improve tissue cutting and coagulation 5
Considerations for Argon Beam Coagulator Use
When using the argon beam coagulator, it is essential to consider:
- The flow rate and distance of the argon gas to ensure effective coagulation and minimize tissue damage 2
- The use of argon gas as an alternative for establishing pneumoperitoneum in case of CO(2) gas delivery failure 2
- The potential benefits of combining argon beam coagulation with other hemostatic agents or methods to improve outcomes 3, 4
Hemostatic Agents and Methods
Various hemostatic agents and methods can be used in conjunction with the argon beam coagulator, including:
