Decreased pulse rate01:14

Decreased pulse rate

858
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Decreasing Function01:27

Decreasing Function

241
A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2​ in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

Decreased Body Temperature01:29

Decreased Body Temperature

1.0K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

6.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

3.7K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

3.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Area of Science:

  • Orthopedic Surgery
  • Vascular Surgery
  • Public Health

Background:

  • Revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA) carry risks of venous thromboembolism (VTE), a serious complication.
  • Current strategies to mitigate VTE risk include rapid recovery programs and thromboprophylaxis guidelines.
  • The incidence and trends of VTE, deep vein thrombosis (DVT), pulmonary embolism (PE), and mortality within 30 days post-rTKA and rTHA require investigation.

Purpose of the Study:

  • To determine the annual incidence and recent trends of 30-day VTE, DVT, PE, and mortality following rTKA and rTHA.
  • To analyze trends in these complications over the study period (2008-2016).
  • To establish baseline data for future research on VTE prevention in revision arthroplasty.

Main Methods:

  • A retrospective analysis of 30,406 patients undergoing rTKA or rTHA from 2008-2016.
  • Data sourced from the National Surgical Quality Improvement Program (NSQIP) database.
  • Calculation of 30-day incidences for VTE, DVT, PE, and mortality, with bivariate and multivariate regression analyses to assess trends.

Main Results:

  • Overall 30-day incidences were 1.2% VTE, 0.9% DVT, 0.4% PE, and 0.5% mortality for rTKA.
  • Overall 30-day incidences were 1.0% VTE, 0.7% DVT, 0.4% PE, and 0.7% mortality for rTHA.
  • No significant changes in VTE, DVT, or PE rates were observed for either rTKA or rTHA during the study period. Mortality significantly decreased for rTHA.

Conclusions:

  • Approximately 1 in 83 rTKA patients and 1 in 100 rTHA patients experienced VTE within 30 days post-surgery.
  • VTE rates following rTKA and rTHA remained largely unchanged between 2008 and 2016.
  • Further research into individualized prophylaxis is needed to optimize VTE prevention in revision arthroplasty procedures.
