General outcomes and risk factors for minor and major amputations in Brazil

[Amputation, from etiology to life project]

Arteritis and trauma are the most frequent causes of amputation. Rehabilitation management is divided into three phases: the immediate post-operative phase, the pre-prosthetic phase and the prosthetic phase.

Achieving Functional Outcomes after Surgical Management of Catastrophic Vasopressor-induced Limb Ischemia

Vasopressor-induced limb ischemia is an unfortunate complication that can occur in patients treated for septic shock. Current literature lacks surgical treatment recommendations for this condition, besides amputation. We describe various reconstructive surgeries and functional outcomes in patients treated surgically for vasopressor-induced limb ischemia.

Methods

We retrospectively reviewed patients who were treated for septic shock and developed vasopressor-induced limb ischemia at our tertiary referral academic medical center. We reviewed presentation, treatment, surgical outcomes, and long-term functional outcomes.

Results

We present three previously healthy patients who developed gangrene of multiple limbs following the use of vasopressors to treat septic shock. Each patient underwent amputations or limb salvage procedures.

Conclusions

Limb ischemia is a devastating complication that can occur after prolonged vasopressor use. The decision to proceed with limb salvage versus amputation of ischemic extremities should be tailored to the individual patient. The main objective should be for the patient to obtain optimal function and quality of life, regardless of the type of surgery.

Quality of Life of Patients With Major Amputations in the Tertiary Care Center of Western Rajasthan: A Prospective Observational Study in 2019-2020

Introduction Amputation of a limb is a loss of physical integrity that has disastrous consequences for a person's mental, physical, and social well-being. Aim We aim to analyze the quality of life (QoL) after major amputations and long-term outcomes. Method and materials A prospective, observational study has been conducted in a health care institute in western Rajasthan from January 2019 to July 2020. This study included 64 patients who had major upper or lower limb amputations. We analyzed the sociodemographic factors of the patients, the type of procedure, postoperative hospital stay, complications, and follow-up status with both the SF-12 and the World Health Organization Quality of Life (WHOQOL)-BREF questionnaires. Mean, median, range, standard deviation, percentages, univariable, and multivariable logistic regression were analyzed with SPSS version 23.0 software (IBM Corp., Armonk, NY). Results The mean age of the study patients was 53.6 years (SD 2.6) and they were mostly male (71.9%). Atherosclerotic peripheral vascular disease (PVD) was the most common indication (37.5%) of amputation, and below-the-knee amputation (46.88%) was the most commonly performed procedure. There was a significant increment in both PCS (p-value= 0.001), MCS scores (p-value=0.0001) of SF-12 and physical (p-value=0.0001) and psychological domains (p-value=0.001) of the WHOQOL-BREF questionnaire in the postoperative period. A total of 83.9% of patients have used prostheses, and 15.6% had mortality. Conclusions Major amputations can significantly affect the quality of life of patients, and all efforts should be made to avoid factors that adversely affect their quality of life.

Study on the Effect of the Five-in-One Comprehensive Limb Salvage Technologies of Treating Severe Diabetic Foot

Objective: To explore the clinical efficacy and advantages of five-in-one comprehensive limb salvage technologies for the treatment of severe diabetic foot ulcer (DFU). Approach: Clinical data for 120 patients with severe DFU treated between January 2012 and December 2017 were analyzed retrospectively. The control group (48 cases) was treated with traditional therapies, including controlling blood sugar, improving microcirculation, preserving nerve function, and dressing changes, whereas the experimental group (72 cases) was treated with traditional therapy combined with additional techniques, such as early and thorough debridement, negative pressure wound therapy, revascularization, and skin graft or flap. Ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO₂), wound healing rate, healing time, ulcer recurrence rate, and amputation rate were recorded. Results: Compared with the control group, the experimental group significantly improved wound healing rate (93.1% vs. 72.9%; p < 0.01), decreased wound healing time (16.2 ± 5.4 days vs. 32.2 ± 7.8 days; p < 0.05), reduced major limb amputation rate (1.4% vs. 10.4%, p < 0.05), and ulcer recurrence rate (5.6% vs. 14.6%; p < 0.05). There were no significant differences in amputation rate between experimental and control group (29.2% vs. 33.3%, p = 0.628). After revascularization, the revascularization group showed significantly improved ABI (0.75 ± 0.21 vs. 0.35 ± 0.16, p < 0.05) and TcPO₂ (36 ± 6 mmHg vs. 15 ± 4 mmHg, p < 0.05). Innovation: We propose a five-in-one comprehensive treatment method, which provides a multidisciplinary cooperative model for comprehensive medical and surgical treatments for DFU. Conclusion: The five-in-one comprehensive limb salvage treatment technologies played a vital role in enhancing the healing rate of severe DFU, shortening the healing time, and reducing the rate of recurrence and major amputation, thus improving the overall quality of life.
