Composition and
Conductivity
Composition of D5W
01
D5W is a hypotonic solution containing 5 grams of dextrose (glucose) per 100 mL of water.
D5W is a hypotonic solution with 5% glucose content.
Composition of Saline
Saline is an isotonic solution containing 0.9% sodium chloride in water.
Saline is an isotonic solution with 0.9% sodium chloride.
Conductivity of D5W
D5W has lower conductivity compared to saline due to the a
bsence of dissociated ions.
D5W has lower conductivity because glucose molecules do not dissociat
e into ions.
Conductivity of Saline
Saline has higher conductivity compared to D5W du
e to the presence of dissolved ions.
Saline has higher conductivity because it contains dissolved sodium and chloride ions.
02
Use in Surgery
Use of D5W in Surgery
D5W is commonly used in laparoscopic or endoscop
ic procedures where electrosurgery is performed.
D5W is used in laparoscopic or endoscopic procedures involvi
ng electrosurgery.
Use of Saline in Surgery
Saline is commonly used for irrigation and insufflation in various surgical procedure
s.
Saline is used for irrigation and insufflation in surgical procedures.
03
Differences in Co
nductivity and S
urgical Use
Conductivity Comparison
Saline has higher conductivity than D5W due to the presen
ce of ions in the solution.
Saline has higher conductivity compared to D5W.
Electrical Dispersion in Surgery
The higher conductivity of saline can cause electrical dispersion during electros
urgery, affecting precision.
Saline's higher conductivity may result in electrical dispersion during electrosurgery.
Safety in Electrosurgery
01
D5W is considered safer for use with electrosurgical devices due to reduced
electrical current dispersion.
D5W is considered safer for use with electrosurgical devices.
Volume and Pressure Considerations
Saline, being isotonic, does not significantly a
ffect fluid balance, while D5W, being hypotoni
c, can cause fluid shifts.
Saline does not significantly affect fluid balance, while
D5W can cause fluid shifts if used in large volumes.
04
Other Uses
Other Uses of D5W
D5W is primarily used for fluid and electrolyte replacement, es
pecially when glucose supplementation is required.
D5W is primarily used for fluid and electrolyte replacement.
Other Uses of Saline
Saline is used for fluid resuscitation,
maintaining blood volume, and as a
vehicle for intravenous medications.
