To investigate whether electrocauterization and a transient tourniquet enhance the efficiency of local anesthesia with epinephrine in surgery for metacarpal fractures.
Approach:
Study Design: 44 consecutive cases of metacarpal fractures were enrolled, utilizing local anesthesia with epinephrine, electrocauterization, and a transient tourniquet.
Data Collection: Data on anesthesia effects, surgical field bleeding, patient discomfort with the tourniquet, surgical outcomes, and other variables were collected.
Key Findings:
No patients felt pain during the surgical period.
Mean discomfort time due to the tourniquet was approximately 16 minutes.
Mean tourniquet release time was approximately 29 minutes.
Little to no bleeding was observed in the surgical field.
Anatomical structures were easily distinguished and dissected.
Postoperative inspections showed no symptoms of inflammation.
Interpretation:
Local anesthesia with epinephrine, electrocauterization, and a transient tourniquet can save time and allow patients to remain awake during major hand surgery.
Limitations:
Small sample size of 44 cases.
Study conducted in a single institution.
Conclusion:
The combination of local anesthesia with epinephrine, electrocauterization, and a transient tourniquet is effective for metacarpal fracture surgery.
