Insights

Postinfusion phlebitis, a common complication of intravenous therapy, can be reduced by controlling admixture osmoticity. Hospital pharmacists can help prevent this condition by ensuring antibiotic formulations are iso-osmotic.

Area of Science:

  • Pharmacology
  • Patient Safety
  • Intravenous Therapy

Background:

  • Postinfusion phlebitis is a frequent complication of intravenous therapy, impacting 25-70% of hospitalized patients.
  • This condition can lead to extended hospital stays and increased healthcare costs.
  • Current intravenous antibiotic products and delivery systems often overlook osmolality, a potential contributing factor.

Purpose of the Study:

  • To discuss the relationship between osmolality and the development of postinfusion phlebitis.
  • To provide hospital pharmacists with actionable strategies for creating iso-osmotic antibiotic formulations.
  • To reduce the incidence of postinfusion phlebitis by addressing osmolality concerns.

Main Methods:

  • Literature review on osmolality and phlebitis.
  • Analysis of current intravenous antibiotic formulations.
  • Development of recommendations for achieving iso-osmotic admixtures.

Main Results:

  • Osmolality is a significant factor in postinfusion phlebitis development.
  • Many antibiotic small-volume parenterals are not iso-osmotic.
  • Pharmacist intervention in controlling admixture osmoticity can mitigate phlebitis risk.

Conclusions:

  • Controlling final admixture osmoticity is a key role for hospital pharmacists in reducing postinfusion phlebitis.
  • Implementing strategies to provide iso-osmotic formulations is crucial for patient safety.
  • Addressing osmolality can decrease the morbidity associated with intravenous therapy.

Osmosis

Approximately 60% to 95% of the weight of living organisms is attributed to water. Therefore, maintaining appropriate water balance within cells is of paramount importance. Osmosis is the movement of water across a semipermeable membrane, such as a cell’s plasma membrane. In living organisms, water plays a crucial role as a solvent—a molecule that dissolves other molecules.Diffusion Versus OsmosisBoth diffusion and osmosis are types of passive transport—cellular transport that does not require...
Tonicity in Animals00:59

Tonicity in Animals

The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

Osmosis and Osmotic Pressure of Solutions

A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally...

Osmosis

Osmosis is the movement of free water molecules through a semipermeable membrane.  The water's concentration gradient across the membrane is inversely proportional to the solutes' concentration. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane, and the membrane limits the diffusion of solutes in the water. Osmosis is a special case of diffusion.
Water, like other substances, moves from a high concentration of free water...
Osmotic Pressure01:26

Osmotic Pressure

Osmosis is a process where solvent molecules move toward a solution through a semipermeable membrane. As the solution dilutes due to the entry of solvent, it expands. This expansion increases the hydrostatic pressure of the solution. When the hydrostatic pressure equals the osmotic pressure, osmosis stops.Osmotic pressure, denoted by Π, is the minimum pressure needed to prevent the solvent from passing into the solution by osmosis. The van 't Hoff equation calculates the osmotic pressure of an...

Factors Influencing Microbial Growth: Osmolarity

Osmolarity is the measure of solute concentration in a solution. It plays a critical role in determining water availability for organisms. Water moves across semipermeable membranes through osmosis, flowing from regions of lower solute concentration (more dilute) to regions of higher solute concentration (more concentrated).In high-solute environments, microbial cells lose water, leading to dehydration and inhibited growth. The extent to which water is available to microbes in such environments...
