Does Articular Pressure Change Vital Signs During Temporomandibular Joint Arthrocentesis?

Objective: The aim of this study was to compare the vital signs as mean arterial pressure and heart rate of patients undergoing two different temporomandibular joint (TMJ) arthrocentesis techniques. Methods: Thirty patients received TMJ arthrocentesis with either double puncture arthrocentesis (DPA) or single puncture arthrocentesis (SPA). Blood pressure and heart rate were assessed preoperatively, during the application of local anesthesia, and at needle insertion into the joint cavity, the 5th and 10th minute of the procedure, and the end of the procedure. Results: The heart rate and mean arterial pressure were highest during anesthesia and needle insertion (P <0.05). Heart rate and mean arterial pressure scores were statistically higher in SPA group. Conclusion: It is necessary to be more cautious in patients receiving SPA as blood pressure and heart rate may increase.
