Dosage and Administration
Dose varies with procedure, onset and depth of anesthesia desired, vascularity of tissues, duration of anesthesia, and condition of patient: A test dose of short-acting local anesthestic containing epinephrine (eg, 3 to 5 mL) should be administered prior to induction of complete block with ropivacaine. Incremental ropivacaine dosing is recommended. Adults:
Lumbar epidural block for surgery:
15 to 30 mL of 0.5% solution
15 to 25 mL of 0.75% solution
15 to 20 mL of 1% solution
Lumbar epidural block for cesarean section:
20 to 30 mL dose of 0.5% solution
15 to 20 mL dose of 0.75% solution
Thoracic epidural block:
5 to 15 mL dose of 0.5% solution
5 to 15 mL dose of 0.75% solution
Major nerve block:
35 to 50 mL dose of 0.5% solution
10 to 40 mL dose of 0.75% solution
Field block: 1 to 40 mL dose of 0.5% solution
Labor pain management: Lumbar epidural: Initial: 10 to 20 mL 0.2% solution; continuous infusion dose: 6 to 14 mL/hour of 0.2% solution with incremental injections of 10 to 15 mL/hour of 0.2% solution
Postoperative pain management:
Peripheral nerve block: Continuous infusion dose: 5 to 10 mL/hour of 0.2% solution (Bagry, 2008; Klein, 2000)

Infiltration/minor nerve block:
1 to 100 mL dose of 0.2% solution
1 to 40 mL dose of 0.5% solution
Refer to adult dosing. Use with caution; initial dose reductions may be necessary.
Note: Dose varies with procedure, depth of anesthesia, vascularity of tissues, duration of anesthesia, and condition of patient. Consider incremental administration with negative aspiration prior to each injection; however, absence of blood in the syringe does not guarantee that intravascular injection has been avoided (Mulroy 2010). Should only be administered under the supervision of a qualified physician experienced in the use of anesthetics. Dosing units variable (mL/kg, mg/kg); use extra precaution to ensure accuracy and minimize potential toxicity.
Central nerve blocks/anesthesia (eg, caudal, lumbar, thoracic): Limited data available:
Caudal block: Infants and Children: Caudal injection: 0.2% (2 mg/mL) solution: 0.5 to 1 mL/kg; some experts suggest a maximum volume of 25 mL (Ivani 1998; Ivani 2002; Jöhr 2015; Kokinsky 2003; Lonnqvist 2000)
Epidural block (eg, lumbar, thoracic): Infants, Children, and Adolescents: Epidural injection 0.2% (2 mg/mL): 0.7 mL/kg. Note: For infants (particularly young infants) if repeat injections necessary, a decreased dose may be necessary to prevent drug accumulation. Some experts suggest if at least 45 minutes since initial dose, reduce dose to 1/3 of the initial or if at least 90 minutes since initial dose, then reduce dose to half of the initial. If additional doses are necessary, doses should be reduced to half of the previous dose (Ivani 1999; Miller 2015).
Epidural, continuous infusion:
Infants <3 months: Epidural injection: Bolus: Usual concentration 0.2% (2 mg/mL) solution: Reported range: 0.5 to 1 mL/kg. In some cases, a more dilute solution (eg, 0.1% [1 mg/mL]) may be required to ensure adequate volume and minimize toxicity. Follow with continuous epidural infusion of 0.2% (2 mg/mL) solution at 0.2 mg/kg/hour (Bosenberg 2005; Hansen 2000; Miller 2015)
Infants ≥3 months, Children, and Adolescents: Epidural injection: 0.2% (2 mg/mL) solution: Bolus: Reported range: 0.5 to 1 mL/kg administered over several minutes (eg, 3 to 5 minutes) followed by continuous epidural infusion at 0.4 mg/kg/hour; in adults, usual rates are 6 to 14 mL/hour of 0.2% solution (Berde 2008; Bosenberg 2005; Hansen 2000)
Peripheral nerve blocks/ local anesthesia: Limited data available: Note: Dose varies with location of block (ie, procedure), depth of anesthesia, vascularity of tissues, duration of anesthesia, and patient parameters (eg, age, weight, condition).
Single injection: The volume of dose (mL/kg) and concentration of solution are site-specific based upon anatomy and variable among patients and procedure (Coté 2013; Miller 2015).
Infants ≥6 months, Children, and Adolescents: Suggested or reported dose volumes presented; not to exceed a suggested maximum dose of 3 mg/kg/dose based on lean body mass; dosing based on extrapolation from adult experience; additional data necessary to more clearly define pediatric upper dose limit. Note: For infants <6 months, dose reductions (eg, by 30%) have been suggested by experts (Coté 2013; Visoiu 2015).

Continuous peripheral nerve block infusion (CPNB) (Dadure 2009; Duflo 2006; Iliev 2016; Visoiu 2014): Infants ≥6 months, Children, and Adolescents:
Initial bolus: 0.2% (2 mg/mL) solution: Dose dependent on nerve catheter location: Commonly reported dose range: ~0.5 to 1.32 mg/kg; some patients and/or catheter/nerve sites may require a higher bolus dose; a trial evaluating 403 pediatric catheter placements reported an overall median bolus for all catheter sites of 1.32 mg/kg (IQR: 0.82 to 1.95 mg/kg); another trial reporting on 339 pediatric catheter placements reported a mean initial bolus dose of 0.49 to 0.98 mg/kg.
Continuous peripheral nerve block infusion: 0.2% (2 mg/mL) solution: Reported mean rate range: 0.11 to 0.25 mg/kg/hour (most experience reported at 0.2 to 0.25 mg/kg/hour); reported IQR range from 403 pediatric catheter placements: 0.12 to 0.33 mg/kg/hour (depending upon catheter site) with a usual duration <72 hours; majority of experience is postoperative pain management following orthopedic procedures including administration via On-Q pump or Ambu Smart-Infuser
Spinal anesthesia: Limited data available: Infant, Children, and Adolescents ≤17 years: Intrathecal (via LP site; L 3-5): Preservative-free 0.5% (5 mg/mL) isobaric solution: 0.5 mg/kg; maximum dose: 20 mg/dose (Kokki 2005)
Administered via local infiltration, epidural block and epidural infusion, or intermittent bolus. Prior to ropivacaine administration, a test dose of short-acting local anesthestic with epinephrine (eg, 3 to 5 mL) should be administered. Incremental ropivacaine dosing is recommended. Do not administer large volume of anesthetic rapidly. The On-Q infusion pump is used to slowly administer local anesthetics (eg, bupivacaine, lidocaine, ropivacaine) to or around surgical wound sites and/or in close proximity to nerves for pre- or postoperative regional anesthesia. When infused directly into the shoulder, destruction of articular cartilage (chondrolysis) has occurred. On-Q pumps should never be placed directly into any joint.
Store at 20°C to 25°C (68°F to 77°F). Infusions should be discarded after 24 hours.

Concerns related to adverse effects:
- CNS toxicity: Careful and constant monitoring of the patient's state of consciousness should be done following each local anesthetic injection; at such times, restlessness, anxiety, tinnitus, dizziness, blurred vision, tremors, depression, or drowsiness may be early warning signs of CNS toxicity. Treatment is primarily symptomatic and supportive.
- Intra-articular infusion related chondrolysis: Continuous intra-articular infusion of local anesthetics after arthroscopic or other surgical procedures is not an approved use; chondrolysis (primarily in the shoulder joint) has occurred following infusion, with some cases requiring arthroplasty or shoulder replacement.
- Methemoglobinemia: Has been reported with local anesthetics; clinically significant methemoglobinemia requires immediate treatment along with discontinuation of the anesthetic and other oxidizing agents. Onset may be immediate or delayed (hours) after anesthetic exposure. Patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, exposure to oxidizing agents or their metabolites, or infants <6 months of age are more susceptible and should be closely monitored for signs and symptoms of methemoglobinemia (eg, cyanosis, headache, rapid pulse, shortness of breath, lightheadedness, fatigue).
- Respiratory arrest: Local anesthetics have been associated with rare occurrences of sudden respiratory arrest.
- Seizures: Convulsions due to systemic toxicity leading to cardiac arrest have also been reported, presumably following unintentional intravascular injection.
- Cardiovascular disease: Use with caution in patients with hypotension, hypovolemia, heart block, or cardiovascular disease; may be at greater risk for toxicity.
- Hepatic impairment: Use with caution in patients with hepatic impairment; may be at greater risk for toxicity.
- Neurological disorders: Use with caution in patients with neurological disorders; may be at greater risk for toxicity.
- Porphyria: Use with caution in patients with acute porphyria; consider use of alternative agents.
- Psychiatric disorders: Use with caution in patients with psychiatric disorders; may be at greater risk for toxicity.
- Renal impairment: Use with caution in patients with severe renal impairment; may be at greater risk for toxicity.
Concurrent drug therapy issues:
- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
- Acutely ill patients: Use with caution in acutely ill; may be at greater risk for toxicity.
- Debilitated patients: Use with caution in debilitated patient; may be at greater risk for toxicity.
- Elderly: Use with caution in the elderly: may be at greater risk for toxicity. Cardiovascular adverse events (bradycardia, hypotension) may be age-related (more common in patients >61 years of age).
- Administration: Intravascular injections should be avoided; aspiration should be performed prior to administration; the needle must be repositioned until no return of blood can be elicited by aspiration; however, absence of blood in the syringe does not guarantee that intravascular injection has been avoided.
- Rapid administration: Ropivacaine is not recommended for use in emergency situations where rapid administration is necessary.
- Trained personnel: Clinicians using local anesthetic agents should be well trained in diagnosis and management of emergencies that may arise from the use of these agents. Resuscitative equipment, oxygen, and other resuscitative drugs should be available for immediate use.
Heart rate, blood pressure, ECG monitoring (if used with antiarrhythmics)
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies. When used for epidural block during labor and delivery, systemically absorbed ropivacaine may cross the placenta, resulting in varying degrees of fetal or neonatal effects (eg, CNS or cardiovascular depression). Fetal or neonatal adverse events include fetal bradycardia (12%), neonatal jaundice (8%), low Apgar scores (3%), fetal distress (2%), neonatal respiratory disorder (3%). Maternal hypotension may also result from systemic absorption. In cases of hypotension, position pregnant woman in left lateral decubitus position to prevent aortocaval compression by the gravid uterus. Epidural anesthesia may prolong the second stage of labor.
