Summary
Pterygopalatine fossa infiltration with lignocaine and adrenaline significantly improves surgical field bleeding during functional endoscopic sinus surgery (FESS). This effective technique enhances surgical visualization with no reported complications.
Area of Science:
- Otorhinolaryngology
- Surgical Anesthesia
Background:
- Functional endoscopic sinus surgery (FESS) is a common procedure performed in the nasal cavity.
- Surgical field bleeding is a significant challenge for endoscopic sinus surgeons, potentially compromising patient safety and surgical outcomes.
Purpose of the Study:
- To evaluate the efficacy of pterygopalatine fossa infiltration with lignocaine and adrenaline in controlling intraoperative bleeding during FESS.
- To assess the impact of this infiltration technique on surgical field quality.
Main Methods:
- A randomized blinded study involving 68 patients undergoing FESS.
- One side of the nasal cavity received pterygopalatine fossa infiltration with 2% lignocaine and 1:80,000 adrenaline; the other side served as the control.
- Surgeons assessed surgical field quality using a standardized scale, blinded to the infiltrated side.
Main Results:
- A statistically significant improvement in surgical field quality was observed on the infiltrated side (p=0.001).
- An approximate 25-30% improvement in surgical field visualization was noted on the infiltrated side.
- Surgical bleeding showed a positive correlation with blood pressure; no complications were associated with the infiltration.
Conclusions:
- Pterygopalatine fossa infiltration with lignocaine and adrenaline is an effective method for reducing surgical field bleeding in FESS.
- This technique can be utilized alongside nasal decongestion or hypotensive anesthesia to optimize the surgical field.
