Experience of nail bed injuries at a tertiary hand trauma unit: a 12-month review and cost analysis

Effect and Mechanism of Dragon's Blood on Wound Healing of Patients with Stress Hand Injury

This study aimed to explore the effect and mechanism of Dragon's Blood on wound healing in patients with a pressure hand injury. A total of 120 patients with pressure hand injury treated in our hospital were randomly divided into two groups. Sixty patients in the control group were dressed with sterile gauze, and 60 patients in the observation group were smeared with blood exhaustion. The clinical effects and serological indexes of the two groups were compared, and the mechanism of wound healing was analyzed. The results showed that the treatment effective rate of the control group was 80% and that of the observation group was 93.33%. The treatment effective rate of the observation group was dramatically higher (P < 0.05). The number of patients with good granulation tissue in the observation group was 53, which was dramatically greater than that in the control group. The number of patients with a small amount of wound exudation was 51, which was dramatically greater than that in the control group (P < 0.05). After treatment, the levels of matrix metalloproteinase (MMP-3), vascular endothelial growth factor (VEGF), and transforming growth factor B1 (TGF-B1) in the observation group increased more dramatically (P < 0.05). The level of tissue inhibitor of metalloproteinase-1 (TIMP-1) decreased to 617.23 ng/L in the observation group, and the degree of reduction was more obvious (P < 0.05). Notably, Dragon's Blood promoted wound healing at the injury site by increasing the levels of MMP-3, VEGF, and TGF-B1and decreasing TIMP-1. The area of wound reduction in the observation group was 0.27 cm², and the reduction was more obvious (P < 0.05). The healing time of pressure hand injury in the observation group was 15.27 days, which was dramatically shorter (P < 0.05). In summary, Dragon's Blood had a good effect on the healing of the injured site in patients with pressure hand injury, which is worthy of promotion.

Rethinking the Need for Nail Plate Removal: A Comparison of the Risks Between Standard Nail Bed Repair and Nonoperative Management

PURPOSE

Nail bed injuries are commonly treated with nail plate removal and repair due to concern for future nail deformity. There is controversy whether this is necessary. We compared the outcomes for adult patients with simple nail bed lacerations who underwent either formal nail bed repair or nonoperative management.

METHODS

A retrospective cohort study was performed of adult patients with nail bed lacerations from 2012 to 2019. Nail bed lacerations were diagnosed in patients with fingertip injuries resulting in subungual hematoma greater than 50% or in any subungual hematoma in the setting of a distal phalanx fracture. All patients included had an intact nail plate. Patients were treated with nail bed laceration repair or nonoperatively without nail plate removal. The primary outcome was the development of a nail deformity. Secondary outcomes included infection, fracture nonunion, and patient-reported functional outcomes using the quick Disabilities of the Arm, Shoulder and Hand score.

RESULTS

Thirty-eight patients with nail bed lacerations were treated nonoperatively, and 40 patients were treated with nail bed repair. The average follow-up time was 4.5 weeks in the office. In addition, 1-year evaluation of patients was performed through telephone interview. The patients in the nonoperative group exhibited no statistically significant difference in the calculated risk for nail deformities compared with the nail bed repair group (13% vs 23%, relative risk = 0.58, P = 0.40, 95% confidence interval = 0.42-1.25). There were no significant differences in secondary outcomes or quick Disabilities of the Arm, Shoulder and Hand scores between groups.

CONCLUSIONS

The authors observed no meaningful difference in the rate of nail deformities in adult patients who underwent nail bed repair compared with those managed nonoperatively.

Clinical application of ultrasound-guided selective proximal and distal brachial plexus block in rapid rehabilitation surgery for hand trauma

BACKGROUND

Anesthesia plays an essential role in the successful surgical procedures for hand trauma. Compared with general anesthesia, brachial plexus block shows lots of benefits for the upper extremity. Specifically, ultrasound-guided selective proximal and distal brachial plexus block may overcome the issues of incomplete block and failure of anesthesia in such circumstances. The present study assessed the efficacy of ultrasound-guided selective proximal and distal brachial plexus block in clinical practice.

AIM

To explore the efficacy of ultrasound-guided selective proximal and distal brachial plexus block in rapid recovery surgery for hand trauma.

METHODS

A total of 68 patients with traumatic hand injuries treated at our hospital from January 2018 to June 2019 were selected. They were divided into an observation group and a control group with 34 patients in each group. The observation group underwent selective brachial plexus block guided by ultrasound and the control group underwent conventional brachial plexus block. The analgesic efficacy, intraoperative complications, wound healing time, and length of hospital stay were compared between the two groups under different anesthesia.

RESULTS

The percentage of cases with analgesia graded as “excellent or very good” was higher in the observation group than in the control group (P < 0.05). Moreover, the incidence of intraoperative complications was lower and the wound healing time and length of hospital stay were shorter in the observation group than in the control group (P < 0.05).

CONCLUSION

Ultrasound-guided selective proximal and distal brachial plexus block has remarkable analgesic efficacy in patients with traumatic hand injuries. It can reduce the incidence of intraoperative complications, promote wound healing, and shorten the length of hospital stay.
