Study Sheds Light on Post-Extraction Bleeding and Emergency Interventions

P. R. CHINA: Post-tooth extraction bleeding is a common complication encountered in dental practices worldwide. While most cases are not life-threatening, the impact on patients’ mental and psychological well-being can be significant. 

In a groundbreaking study published in the Research in Medical and Health Professions journal, researchers from Peking University School and Hospital of Stomatology have shed light on the risk factors associated with post-extraction bleeding and evaluated emergency intervention strategies.

Key Findings

The study, led by Dr. Ai-Ping Ji, employed advanced statistical methods, including chi-squared tests, rank sum tests, and logistic regression analyses, to examine a comprehensive dataset of clinical cases from 2017 to 2022. The findings revealed crucial insights into the factors influencing post-extraction bleeding and the effectiveness of various treatment modalities.

Risk Factors

Multivariate analyses unveiled an increased susceptibility to bleeding among male patients and individuals aged 60 years or older. As Dr. Ji stated, “It is imperative to prioritize the scrutiny of risk factors associated with post-tooth extraction hemorrhage, with the aim of preemptively averting incidences of bleeding subsequent to tooth extraction.”

The adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) were as follows:

• Male patients: OR = 1.54 (95% CI: 1.34–1.77, P < 0.001)
• Patients aged 60 or older: OR = 0.74 (95% CI: 0.59–0.91, P = 0.005)
• Patients aged 70 or older: OR = 0.58 (95% CI: 0.42–0.80, P = 0.001)

Emergency Interventions

The study also evaluated the effectiveness of various treatment modalities for patients experiencing substantial blood loss. Multivariate logistic regression analysis revealed the following ORs compared to patients with minimal blood loss:

• Iodoform gauze strips: OR = 220.80 (95% CI: 151.43–321.95, P < 0.001)
• Sutures: OR = 69.40 (95% CI: 46.11–104.44, P < 0.001)
• Collagen: OR = 52.78 (95% CI: 34.66–80.38, P < 0.001)
• Compression: OR = 12.85 (95% CI: 9.46–17.45, P < 0.001)

Significance and Future Implications

The study’s findings underscore the importance of identifying risk factors for post-extraction bleeding and implementing appropriate emergency interventions. As Dr. Ji emphasized, “It is paramount to offer expert and tailored emergency interventions designed to address diverse case scenarios.”

The research team plans to further explore the impact of preoperative assessments and intraoperative procedures on post-extraction bleeding, aiming to develop comprehensive guidelines for dental practitioners worldwide.
