Factors determining poor prognostic outcomes following diabetic hand infections

Predictors of Digital Amputation in Diabetic Patients With Surgically Treated Finger Infections

BACKGROUND

Diabetes is a well-established risk factor for severe digital infection, and patients are more likely to require digital amputation for adequate source control. This study aims to identify factors predictive of digital amputation compared with preservation in patients with diabetes who present with surgically treated finger infections.

METHODS

Current Procedural Terminology (CPT) and International Classification of Diseases Versions 9 and 10 (ICD-9/10) databases from a single academic medical center were queried to identify patients with type 1 or type 2 diabetes mellitus who underwent surgical treatment in the operating room for treatment of a digital infection from 2010 to 2020. Electronic medical records were reviewed to obtain historical and acute clinical variables at the time of hospital presentation. Bivariate and multivariable regression were used to identify factors associated with amputation.

RESULTS

In total, 145 patients (61 digital amputation, 84 digital preservation) met inclusion criteria for this retrospective cohort study. Mean hospital stay was 6 days, and the average patient underwent 2 operations. Multivariable analysis revealed that the presence of osteomyelitis, ipsilateral upper extremity dialysis fistula, end-stage renal disease, and vascular disease each had significant independent predictive value for amputation rather than digital preservation.

CONCLUSIONS

Digital amputation is common in the setting of diabetic finger infection. The 4 variables found to independently predict the outcome of amputation can be understood as factors which decrease the likelihood of successful digital salvage and increase the potential consequence of ongoing uncontrolled infection. Further study should focus on clinical factors affecting surgical decision making and how the treatment rendered affects patient outcomes.

Reconstruction of soft tissue defects of hand: A systematic approach

Background and Objective

A thorough insight into the management of hand injuries can shape the approach of a surgeon in order to achieve optimal outcomes for the patients. The aim of this study was to share our experience in reconstruction of the hand and establishing an algorithm for classification and treatment of hand injuries.

Methods

This is a descriptive cross sectional study and was conducted from January 2020 to August 2022 at Burns and Plastic Surgery center, Peshawar. Data was collected from medical records about the patient demographics, mechanism of injury and type of procedures done. Defect size was classified into small (<5cm), medium (5cm to 10 cm) and large (>10cm). The defect site and size was cross tabulated against the method of soft tissue reconstruction in order to make the algorithm for reconstruction of hand injuries. Data was analyzed using SPSS.

Results

The study population included 41 (75.9%) male and 13 (24.1%) female patients, mean age 31.56±14.1. Machine injuries (33.3%) and electric burns (24.1%) were the most common cause of hand soft tissue defects. The most commonly performed flap was Posterior introsseous artery (PIA) flap, followed by First dorsal metacarpal artery (FDMA) flap. Flap necrosis was observed in three cases (5.6%).

Conclusion

This treatment algorithm for coverage of soft tissue defects in hand injuries will help with the decision making process of hand reconstruction and has didactic value for novice surgeons. It will also form the foundation for further work on this aspect of hand injuries.

Treatment of hand infections using WALANT -when the anesthesiologist is not available: A retrospective cohort study

Backround

The aim of this study was to determine, if Wide Awake Local Anesthesia No Tourniquet (WALANT) can be used as an alternative method of providing anesthesia in management of deep infections of the hand. Since the advent of WALANT in 2003, infections of the hand have been regarded as a contraindication to its use. Occasional shortage of anesthesiologic manpower, especially during busy call hours and the current COVID-19 pandemic can lead to delay of treatment where urgent surgery is needed, to prevent progress of an infection, that can result in severe morbidity.

Methods

In the period from 2015 to 2020, 16 patients with various infections of the hand underwent 17 operations using WALANT in a Hand Trauma and Replantation Center (HTRC) in Germany. Retrospective cohort analysis of their operation reports, with emphasis on location of infection, time and duration of the operation, intraoperative incidents and complications were carried out. We also evaluated the need for revision surgery or necessity to convert to general anesthesia and factors causing delay till the time of surgery.

Results

No case of inadequate analgesia, the need to convert to general anesthesia, ischemic events or cardiovascular complications with the use of the WALANT solution containing adrenaline and lidocaine in the treatment of deep tissue infections.

The highest priority of limb preservation was ensured as no patient progressed to amputation of a digit or the hand. There was a statistically significant difference (p≤0.01) in delay from the time of admission until surgery of up to 9h24 m (SD±3h34 m) during the week and 4h10 m (SD±2h28 m) during the weekend.

Conclusion

The status of infection as an absolute contraindication to the use of WALANT should be revised. Especially when human resources are limited, WALANT is an adequate technique to enable quick anesthesia for urgent treatment to prevent progression of hand infections.

•

Wide Awake Local Anesthesia No Tourniquet can be used to treat deep hand infections.

•

In the COVID-19 pandemic alternative ways of providing anesthesia are needed.

•

Absolute contraindication to the use of WALANT should be reevaluated.

•

“time is function”, urgent treatment remains key in management of hand infections.

Surgical outcomes of diabetic hand infections in Lagos, Nigeria

Background

Hand infections in diabetics can be a major cause of functional impairment. In patients with Tropical Diabetic hand syndrome prompt surgical intervention may salvage the hand, but return to premorbid function remain a challenge.

Objectives

A retrospective study of consecutive diabetic patients with hand infections was done in 2 tertiary institutions in Lagos, Nigeria to identify the epidemiology, modes of presentation, types of surgical intervention and outcomes of treatment.

Results

Twenty one patients were studied over a 5 year period. ten males, eleven females. All were type 2 Diabetes. 52.4%(11) were diagnosed less than a year prior to presentation. 61.9%(13) had digit/hand gangrene on presentation. All operated patients (20) had wound debridements. 52.5% (11) digit/hand amputations and this was the commonest surgical procedures done. Other surgeries done include skin grafts and `flap reconstructions. There was a 19% mortality rate. Less than a fifth were able return to their premorbid occupation after 3 months. But all had reduced range of motion in the interphalangeal joints in the adjacent digits.

Conclusions

There is a high morbidity rate for hand infections in the diabetic, even though majority of the hands were salvaged, most patients were unable to return to their premorbid occupation at 3 months.
