Summary
Body mass index (BMI) increased one year after amputation surgery, with higher pre-surgical BMI linked to poorer mobility and prosthetic use. Interventions are needed to manage weight post-amputation.
Area of Science:
- Rehabilitation Medicine
- Clinical Research
- Obesity Studies
Background:
- Lower-extremity amputation patients often present with overweight and obesity.
- Weight gain is a common issue in the year following amputation surgery.
Purpose of the Study:
- To analyze body mass index (BMI) changes in the year after amputation.
- To investigate the relationship between BMI and mobility/prosthetic device use.
Main Methods:
- Prospective study of 87 patients undergoing dysvascular amputation.
- Self-reported BMI, mobility, and prosthetic use assessed pre-surgery and at 6 weeks, 4, and 12 months post-amputation.
- BMI adjusted for limb weight loss.
Main Results:
- Adjusted BMI decreased initially but increased by 12 months post-amputation.
- No significant BMI differences observed based on amputation level.
- Higher pre-surgical BMI correlated with less prosthetic walking time (4 months) and poorer mobility (12 months).
Conclusions:
- Body mass index (BMI) rises one year post-amputation.
- Elevated pre-surgical BMI is associated with reduced mobility and prosthetic device utilization.
- Weight management interventions are crucial for improving outcomes in amputees.

01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:15Veins of Lower Limbs
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
