Predicting Pain Intensity after Mandibular Third Molar Surgery using Cold Pressor Testing: A Quasi-Experimental...

Area of Science:

• Oral and Maxillofacial Surgery
• Pain Management
• Anesthesiology

Background:

• Patient pain perception varies significantly, leading to suboptimal post-operative pain management.
• Subjective pain experiences necessitate objective pre-operative measures to predict post-operative pain intensity.
• Understanding pre-operative pain behavior can improve pain control and patient quality of life after surgery.

Purpose of the Study:

• To predict post-operative pain intensity following third molar surgery.
• To correlate pre-operative cold pressor test responses with post-operative pain perception.
• To identify potential predictors of severe post-operative pain.

Main Methods:

• A quasi-experimental study involving 43 adult participants undergoing third molar surgery.
• Pre-operative cold pressor testing to assess sensory-discriminative and affective pain dimensions.
• Post-operative pain intensity recorded at intervals, analyzed using ordinal regression and Spearman's rank correlation.

Main Results:

• Cold pressor test revealed median pain threshold of 20s and median pain tolerance of 33s.
• Peak post-operative pain scores were observed at 3 hours after surgery.
• Pre-operative cold pressor test variables significantly predicted 3-hour post-operative pain intensity.

Conclusions:

• The sensory-discriminative and affective dimensions of pain response to a cold pressor test are significant predictors of peak post-operative pain.
• Pre-operative pain assessment using cold pressor testing can aid in managing post-operative pain after third molar surgery.
• This predictive capability can help in allocating resources for effective pain management.
