Background
Over the past 4 years, aesthetic surgery, notably liposuction, has substantially increased. Tumescent liposuction, a popular technique, has two variants—true tumescent liposuction (TTL) and semi-tumescent liposuction. While TTL reduces risks, it has limitations. There is no literature reported on semi-tumescent liposuction under deep sedation using the propofol–ketamine protocol, which is proposed as a potentially safe alternative.
Methods
The retrospective analysis covered 8 years and included 3094 patients performed for tumescent liposuction under deep sedation, utilizing the propofol–ketamine protocol. The evaluation of patient safety involved an examination of potential adverse events with a specific focus on respiratory issues related to sedation, including instances of mask ventilation.
Results
Among the 3094 cases, no fatalities were recorded. Noteworthy events included 43 mask ventilation instances, primarily occurring in the initial 10 min. Twelve cases experienced surgery cancellation due to various factors, including respiratory issues. Three patients were transferred to upper-level hospitals, while another three required blood transfusions. Vigilant management prevented significant complications, and other adverse events like venous thromboembolism (VTE), fat embolism, severe lidocaine toxicity, and so on were not observed.
Conclusions
The analysis of 3094 tumescent liposuction cases highlighted the overall safety profile of the propofol–ketamine protocol under deep sedation. The scarcity of severe complications underscores its viability. The study emphasizes the significance of thorough preoperative assessments, careful patient selection, and awareness of potential complications. Prompt interventions, particularly in addressing sedation-related respiratory issues, further contribute to positive outcomes for patients.
