ERAS entails the undertaking of several procedures and following some principles to decrease the effect of these responses and improve patient outcomes. Key factors consist of minimally invasive approach, removal of the nasogastric tube, no drain placement, multimodal analgesia, early mobilization and early resumption of normal diet. These should result in improved outcomes, including the decreased length of stay, and a lower rate of complications.
At PCCI, beginning from 2015, more than 2000 procedures have undergone through the ERAS protocol, including urological, gynecological, and general surgery procedures. This has resulted in a significant reduction of length of hospital stay from 4.24 to 2.88 days, p<0.05 in radical prostatectomy, and from 4.8 to 3.84 days, p<0.05 in partial nephrectomy. However, the postoperative complication and readmission rate has remained stable.
According to Dr. Pignot and Dr. Brun, there are three pillars to the ERAS strategy:
- Minimally invasive surgery
- Multi-disciplinary teamwork – This requires standardized perioperative care specific to each surgical procedure
- Patient factors – including education and sufficient information, securing a return to routine home life, and a hospital-city network, through external nurse networks.
- No bowel preparation
- Minimally invasive surgery
- No placement of a drain
- Early diet reintroduction
- Early mobilization
Figure 1 – ERAS protocol in PCCI:
Dr. Brun provided some principle factors in the field of anesthesia in the ERAS protocol. These included the usage of short-acting drugs and monitoring, optimal pain management, including multimodal anesthesia, use of local anesthetics, and morphine sparing. Additionally, optimal postoperative nausea and vomiting management is a key factor, and hemodynamic protocol unique for ERAS is used with the most important factor being goal-directed fluid therapy. It also entails protective ventilation with low volume and low pressure. Lastly, optimal postoperative pain management with nonsteroidal medications being the first line of therapy, in an attempt to avoid opiates.
