Abstract

Insights

Serratus anterior plane block (SAPB) effectively reduces post-operative pain and hospital stay for patients undergoing minimally invasive heart surgery (MIHS). This pain management technique offers significant benefits compared to continuous wound infiltration (CWI).

Area of Science:

  • Anesthesiology and Pain Management
  • Cardiothoracic Surgery
  • Regional Anesthesia Techniques

Background:

  • Minimally invasive heart surgery (MIHS) is associated with significant and prolonged post-operative pain.
  • Effective pain management is crucial for patient recovery and outcomes following MIHS.
  • Current pain management strategies require optimization for improved patient comfort and reduced complications.

Purpose of the Study:

  • To compare the efficacy of serratus anterior plane block (SAPB) versus continuous wound infiltration (CWI) for managing post-operative pain after MIHS.
  • To evaluate the impact of SAPB and CWI on patient-reported pain scores and analgesic consumption.
  • To assess the effect of these pain management techniques on length of hospital and intensive care unit stay.

Main Methods:

  • A retrospective, monocentric study included patients undergoing MIHS between November 2016 and April 2017.
  • Two groups were compared: 20 patients receiving SAPB (single injection of ropivacaine) and 26 patients receiving CWI (catheter with continuous ropivacaine infusion).
  • Post-operative morphine consumption, visual analog scale (VAS) pain scores, and length of stay were recorded for 48 hours.

Main Results:

  • Patients in the SAPB group demonstrated significantly lower morphine consumption and VAS scores compared to the CWI group (p < 0.01).
  • The length of stay in both the intensive care unit and the hospital was significantly reduced in the SAPB group.
  • SAPB proved to be a more effective analgesic strategy for post-MIHS pain.

Conclusions:

  • Serratus anterior plane block (SAPB) is an effective method for reducing post-operative pain in patients undergoing minimally invasive heart surgery (MIHS).
  • SAPB offers advantages over continuous wound infiltration in terms of pain reduction and decreased hospital resource utilization.
  • The findings support the use of SAPB as a primary analgesic modality for MIHS patients.

Work Done Over an Inclined Plane

The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

Body Planes01:06

Body Planes

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Coordinate Plane01:21

Coordinate Plane

The Cartesian coordinate plane is a fundamental structure in mathematics that enables the visualization of relationships between numerical values in two dimensions. It is formed by two intersecting number lines: a horizontal x-axis and a vertical y-axis. These axes meet at the origin, the point where both values are zero. Their intersection divides the plane into four quadrants labeled in a counterclockwise direction starting from the upper right.An ordered pair of numbers represents every...

Plane Electromagnetic Waves I

The existence of combined electric and magnetic fields that propagate through space as electromagnetic (EM) waves is the most significant prediction of Maxwell's equations. As Maxwell's equations hold in free space, the predicted electromagnetic waves do not require a medium for their propagation. An EM wave comprises an electric field, defined as the force per charge on a stationary charge, and a magnetic field, which is the force per charge on a moving charge.
The EM field is assumed to be a...

Transformation of Plane Stress01:18

Transformation of Plane Stress

Studying stress transformation is essential in understanding how stress components within a material, like a cube under plane stress, change with rotation. This change is analyzed by considering a prismatic element within the cube. As the element rotates, the stress components acting on it—both normal and shearing stresses—change in magnitude and orientation. This change is quantified using trigonometric functions of the rotation angle, relating the forces acting on the rotated element's...
