Cardiomyopathy VII: Pre and Post Operative Nursing Management

268
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

General Anesthesia: Overview01:24

General Anesthesia: Overview

556
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Insufficient Sleep and Sleep Deprivation

816
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Summary

Post-operative delirium (POD) is common after cardiac surgery (CS). Poor sleep quality and shorter sleep duration are linked to a higher risk of developing POD in these patients.

Area of Science:

  • Medical Research
  • Cardiology
  • Neurology

Background:

  • Post-operative delirium (POD) affects up to 55% of cardiac surgery (CS) patients.
  • Perioperative sleep disorders (PSD) are prevalent, impacting up to 60% of surgical patients.
  • Understanding the link between PSD and POD in CS is crucial for patient outcomes.

Purpose of the Study:

  • To systematically review and meta-analyze the association between perioperative sleep disorders (PSD) and post-operative delirium (POD) in cardiac surgery (CS) patients.
  • To quantify the impact of sleep quality on POD incidence during hospitalization after CS.

Main Methods:

  • A systematic review and meta-analysis were conducted, searching five major databases.
  • Included studies focused on adults undergoing any open-heart CS, assessing sleep and POD.
  • A random effects model was used to pool data from 33 included studies (63% observational).

Main Results:

  • Increased Pittsburgh Sleep Quality Index (PSQI) scores correlated with a higher likelihood of POD (SMD = 0.73).
  • Lower total sleep time was significantly associated with an increased risk of POD (SMD = -0.68).
  • Poor sleep quality, insomnia, and sleep-disordered breathing are identified as major risk factors for POD post-CS.

Conclusions:

  • Perioperative sleep disorders are significant risk factors for post-operative delirium in cardiac surgery patients.
  • Interventions targeting sleep quality may help mitigate POD risk.
  • Further research is needed to understand sleep recovery timelines and effective interventions post-cardiac surgery.
