Replacement of extracellular fluid and electrolytes; provides buffering capacity via bicarbonate precursor (acetate) and maintains physiological p H.
PHYSIOSOL is a sterile, non-pyrogenic isotonic solution of electrolytes (sodium, potassium, calcium, magnesium, chloride, acetate, and gluconate) in water for injection. It serves as a source of water and electrolytes to expand extracellular fluid volume and maintain osmotic balance. The acetate and gluconate ions are metabolized to bicarbonate, providing an alkalinizing effect.
Intravenous replacement of intravascular volume and electrolytes in patients with normal or slightly acidic p H,Maintenance of fluid and electrolyte balance during surgery or in critical care,Correction of hypovolemia when isotonic fluid administration is appropriate
Intravenous solution for fluid and electrolyte replacement in patients with isotonic or hypotonic dehydration,Maintenance of fluid and electrolyte balance during surgery or in postoperative patients,Vehicle for administration of compatible medications
Intravenous infusion, rate adjusted based on clinical status and electrolyte needs; typical adult dose is 500-1000 m L over 1-2 hours.
Intravenous infusion; dose based on fluid and electrolyte requirements; typical adult dose: 500-1000 m L/h as needed to maintain hydration and electrolyte balance.
Not applicable; components follow first-order kinetics with rapid redistribution. Lactate half-life ~15-30 minutes (hepatic metabolism).
Not applicable (physiologic solution); infused electrolytes and water distribute and are eliminated with kinetics dependent on renal function; terminal half-life reflects water turnover (~3-6 days in healthy adults).
Acetate is metabolized primarily in the liver and muscles to bicarbonate.
The acetate and gluconate ions are metabolized in the liver and peripheral tissues, primarily via the tricarboxylic acid cycle, to bicarbonate. Electrolytes (sodium, potassium, calcium, magnesium, chloride) are not metabolized but are excreted or reabsorbed as per physiological needs.
Primarily renal; >95% of infused ions (sodium, chloride, lactate, calcium, magnesium) are excreted unchanged in urine. Biliary/fecal elimination negligible (<1%).
Renal excretion of water and electrolytes; >95% of administered volume is excreted unchanged by kidneys within 24 hours; minimal (<5%) fecal or biliary elimination.
Negligible (<1%); ions are free in plasma (no significant protein binding).
Negligible (<1%); electrolytes are not bound to plasma proteins.
0.4 L/kg; distributes mainly in extracellular fluid (ECF).
Approximately 0.55 L/kg (total body water); distributes into extracellular fluid (0.2 L/kg) and intracellular water (0.4 L/kg).

No dose adjustment required; monitor serum electrolytes and fluid balance closely in renal impairment; adjust infusion rate based on renal function to avoid fluid overload.
No specific Child-Pugh based adjustments; use with caution in hepatic impairment due to risk of fluid overload.
No specific dose adjustment required; monitor serum electrolytes and acid-base balance in severe hepatic impairment.
Weight-based dosing: 5-10 m L/kg intravenous infusion over 1-2 hours, not to exceed 30 m L/kg/day.
Intravenous infusion; dosing based on body weight; typical dose: 10-20 m L/kg for acute replacement, then adjust based on maintenance requirements; monitor electrolyte levels.
Use with caution due to increased risk of fluid overload and electrolyte imbalance; adjust rate and volume based on renal function and comorbidities, typical initial dose 500 m L over 2-3 hours.
Use with caution; start with lower end of dosing range; monitor for fluid overload, electrolyte disturbances, and renal function due to age-related changes.
None.

No food interactions are relevant as Physiosol p H 7.4 is not ingested. It is used exclusively for topical irrigation during medical procedures.
No specific food interactions. However, consider overall fluid and electrolyte intake from diet, especially sodium and potassium, to avoid imbalances.
Physiosol p H 7.4 (balanced electrolyte solution) is considered low risk for teratogenicity. There are no known fetal risks associated with its use in any trimester, as it is a physiological solution. However, large volumes or rapid administration could theoretically cause maternal electrolyte imbalances, which may indirectly affect the fetus.
Physiosol in plastic container is a sterile, non-pyrogenic isotonic solution of electrolytes and water. It contains no known teratogenic agents. There are no adequate and well-controlled studies in pregnant women. Animal reproduction studies have not been conducted with this solution. Therefore, it should be used during pregnancy only if clearly needed. No specific fetal risks have been identified for any trimester when used as directed.
Physiosol p H 7.4 is compatible with breastfeeding. No M/P ratio is available; however, components are normal plasma constituents and unlikely to be excreted into breast milk in clinically significant amounts.
Safety in breastfeeding has not been established. Since Physiosol is a balanced electrolyte solution, it is unlikely to pose significant risk to the nursing infant. However, caution is advised. The milk-to-plasma (M/P) ratio is not available.
No specific dose adjustment is required for pregnancy. However, consider increased plasma volume and glomerular filtration rate in pregnancy; standard dosing is appropriate, but monitor for volume overload.
No specific dosing adjustments are required for pregnancy based on pharmacokinetic changes. However, pregnant patients may have increased plasma volume, and fluid and electrolyte requirements should be individualized. Caution is advised in preeclampsia or conditions with fluid overload.
Physiosol p H 7.4 is a balanced crystalloid solution used for irrigation, not for systemic administration. In the operating room, it is preferred for peritoneal lavage due to its neutral p H, which minimizes tissue irritation. Do not use for intravenous infusion; verify labeling to avoid confusion with IV solutions. Warm to body temperature before use to prevent hypothermia during large-volume irrigation.
Physiosol in plastic container is a balanced electrolyte solution for intravenous administration, primarily used for replacement of extracellular fluid losses. Monitor for signs of fluid overload, especially in patients with heart failure or renal impairment. The plastic container may leach phthalates; use with caution in neonates and pregnant women. Do not administer if solution is discolored or contains particulate matter.
This solution is used to rinse body cavities during surgery, not for intravenous use.,You may feel a cooling sensation during irrigation; this is normal.,Report any signs of infection at the surgical site, such as redness, swelling, or discharge.,Do not attempt to use this solution at home; it is for hospital use only.
This solution is given intravenously to replace fluids and electrolytes.,Report any signs of allergic reaction, such as rash, itching, or difficulty breathing.,Notify your healthcare provider if you experience swelling, shortness of breath, or rapid weight gain.,Do not stop the infusion without consulting your doctor.
