Chloroprocaine

Spinal anaesthesia is an established component of perioperative management for fast-track lower limbs arthroplasty. Short-acting local anaesthetics may present an interesting option for primary non-complicated knee (TKA) and hip (THA) arthroplasty. We describe the perioperative outcomes in patients operated under fixed 50 mg spinal chloroprocaine for total hip and knee replacement. In this retrospective case series study, 65 patients were analysed (median age 65 years, 55% females, benefit from THA ( n = 31), TKA ( n = 25), and unicompartmental knee arthroplasty ( n = 9))...

Background and Aims: Chloroprocaine is a short-acting local anaesthetic agent for spinal anaesthesia (SA) that has been used in day care surgeries due to its faster recovery characteristics and faster discharge rates compared to other local anaesthetics. This study aimed at finding out its efficacy for the same as compared to general anaesthesia (GA). Material and Methods: This observational study was conducted on 60 patients belonging to the American Society of Anaesthesiologists (ASA) physical status I and II who underwent short elective urological procedures (<60 min) under GA (group GA) as per standard of care in our hospital (n = 30) and SA (group SA) with 50 mg 1% isobaric 2-Chloroprocaine (n = 30)...

BACKGROUND: Plain 2-chloroprocaine , a rapid acting amino-ester-type local anaesthetic, is used in short ambulatory procedures under spinal anaesthesia. The ED 95 of 2-chloroprocaine for lower limb surgery has not yet been defined. Moreover, patients' body height could influence the effects of the administered dose. OBJECTIVES: The aim of this study was to determine the ED 95 of plain 2-chloroprocaine based on the height of patients undergoing ambulatory knee arthroscopy under spinal anaesthesia using the continual reassessment statistical method (CRM)...

Introduction Day-care surgery has become an immensely popular modality of treatment throughout the globe. Ureteroscopic lithotripsy (URSL) surgery is commonly performed on a day-care basis, and the duration of surgery ranges from 15 minutes to 45 minutes. URSL is routinely done under spinal anaesthesia. Spinal anaesthesia with conventional drugs has its problems like delayed regression and urinary retention, necessitating a longer hospital stay, thereby increasing the time and resources needed. For day-care surgery, short-acting local anaesthetics have a quicker onset with fewer side effects, and drugs that ensure quicker hospital discharge are more often preferred over long-acting anaesthetics...

BACKGROUND: Intraperitoneal chloroprocaine has been used during cesarean delivery to supplement suboptimal neuraxial anesthesia for decades. The short in vitro half-life of chloroprocaine (11-21 seconds) has been cited to support the safety of this approach. However, there are no data regarding the rate of absorption, representing patient drug exposure, through this route of administration. Accordingly, we designed a study to determine the in vivo half-life of intraperitoneal chloroprocaine and assess clinical tolerability...

BACKGROUND: Bupivacaine is commonly used in spinal anesthesia for cervical cerclage placement, but its long duration of action can delay hospital discharge. Chloroprocaine has a short duration of action and has re-emerged as an agent for ambulatory neuraxial anesthesia. There are limited data comparing intrathecal bupivacaine and chloroprocaine when used for cerclage placement. This retrospective study compares the time to hospital discharge between these drugs when used in spinal anesthesia for cervical cerclage placement...

BACKGROUND: Chloroprocaine is a short-acting local anesthetic that has been used for spinal anesthesia in outpatient surgery. There is limited experience with spinal chloroprocaine for prophylactic cervical cerclage placement. We sought to determine the effective dose of intrathecal chloroprocaine for 90% of patients (ED90) undergoing prophylactic cervical cerclage placement. We hypothesized that the ED90 of intrathecal chloroprocaine when combined with 10-ug fentanyl would be between 33 and 54 mg...

BACKGROUND: A short acting spinal anesthetic facilitates smooth flow since quick recovery of motor function will facilitate unassisted ambulation. The aim of this study was to estimate the effective dose (ED90) of intrathecal 2-chloroprocaine 1% in outpatient knee arthroscopy. METHODS: Two cohorts were included in two different hospitals. In cohort I, a randomized biased-coin up-and-down design with 40 patients was used to find the ED90. Four dose-levels of plain 2-chloroprocaine 1% were used: 25, 30, 35 and 40 mg...

Regional anesthesia is being used more frequently in the practice of pediatric anesthesia including neonates and infants. While generally safe and effective, adverse effects may occur related to catheter placement or its subsequent use. We present the rare occurrence of high motor blockade with apnea following the administration of a bolus dose of the local anesthetic agent, 2-chloroprocaine, into the thoracic epidural catheter of a 4-week-old, 2.2-kg former premature neonate. The patient had an epidural catheter that had been threaded from the caudal space to the thoracic level to provide analgesia following an abdominal surgical procedure...

PURPOSE: Chloroprocaine provides spinal anesthesia for day-case surgery lasting up to 40 minutes. Intravenous and spinal dexmedetomidine can prolong spinal anesthesia, but no data are available for the combination with chloroprocaine. This double-blind randomized controlled trial compares chloroprocaine with spinal or intravenous dexmedetomidine regarding block characteristics, micturition, and discharge times. PATIENTS AND METHODS: After ethical approval and informed consent, 135 patients scheduled for knee arthroscopy were randomized to receive either 40mg spinal chloroprocaine (Chloro-group), 40mg chloroprocaine with 5 mcg spinal dexmedetomidine (Spinal Dex-group) or 40mg chloroprocaine with 0...

Spinally-administered local anesthetics provide effective perioperative anesthesia and/or analgesia for children of all ages. New preparations and drugs require preclinical safety testing in developmental models. We evaluated age-dependent efficacy and safety following 1 % preservative-free 2-chloroprocaine (2-CP) in juvenile Sprague-Dawley rats. Percutaneous lumbar intrathecal 2-CP was administered at postnatal day (P)7, 14 or 21. Mechanical withdrawal threshold pre- and post-injection evaluated the degree and duration of sensory block, compared to intrathecal saline and naive controls...

BACKGROUND: Epidural anesthesia in infants undergoing open abdominal surgery has the potential to reduce opioid consumption, lower pain scores, and expedite tracheal extubation. We evaluated associations between use of continuous epidural chloroprocaine and improved intra- and post-operative outcomes. METHODS: This matched retrospective cohort study first identified 24 patients who between April 2018 through December 2019 were treated with a caudal catheter and epidural chloroprocaine infusion for a laparotomy at postnatal age of 6 months or less...

BACKGROUND: Cervical cerclage is a short ambulatory procedure. For spinal anesthesia, local anesthetic agents with rapid postoperative resolution are desired. We hypothesized that in combination with fentanyl, intrathecal 2-chloroprocaine would produce earlier resolution of motor block, resulting in shorter time to meet recovery room discharge criteria than hyperbaric bupivacaine. METHODS: Women undergoing cervical cerclage with spinal anesthesia were randomized to receive intrathecal 2-chloroprocaine 3% 50 mg or hyperbaric bupivacaine 0...

BACKGROUND: With increasing focus on outpatient care, there has been an increased demand for short-acting spinal anesthetics, facilitating early recovery and mobilization of the patient. AIMS: The aim of the study was to compare 1% chloroprocaine, characterized by short latency and short duration with 0.5% levobupivacaine, which has shown to preserve motor function at low concentrations, with recovery from motor block as the primary objective and recovery from sensory block and hemodynamic stability as secondary objectives...

Chloroprocaine is a short-acting local anaesthetic with a rapid onset of action and an anaesthesia duration up to 60 min. In this pivotal study success rates, onset and remission of motor and sensory block and safety of chloroprocaine 2% was compared to ropivacaine 0.75% for short-duration distal upper limb surgery with successful block rates as primary outcome. The study was designed as a prospective, randomised, multi-centre, active-controlled, double-blind, parallel-group, non-inferiority study, performed in 4 European hospitals with 211 patients scheduled for short duration distal upper limb surgery under axillary plexus block anaesthesia...

Background and Aims: Preservative free 1% 2-chlorprocaine is a short acting local anaesthetic agent suitable for day care surgical procedures. Potentiation of analgesic action of intrathecal local anaesthetics by the addition of opioids is well known. In this study, we investigated the effect of intrathecal fentanyl as an adjuvant to 1% 2-chloroprocaine (2-CP) in parturients undergoing elective lower segment caesarean section (LSCS). Methods: This prospective randomised comparative study was performed on 150 healthy, term parturients planned for elective low risk LSCS, divided into two equal groups...

PURPOSE: The aim of this study was to compare intrathecal 1% chloroprocaine with 2% hyperbaric prilocaine in the setting of ambulatory knee arthroscopy. We hypothesized that complete resolution of the sensory block was faster with chloroprocaine. METHODS: Eighty patients scheduled for knee arthroscopy were included in this prospective randomized double-blind study. Spinal anesthesia was performed with either chloroprocaine (50 mg) or hyperbaric prilocaine (50 mg)...

Continuous epidural anesthesia is considered the best modality for pain relief during labor, local anesthetic allergy is an uncommon occurrence but if a patient has an allergy to bupivacaine or lidocaine owing to its cross-reactivity with bupivacaine then it becomes very challenging to manage labor analgesia. A direct challenge test to rule out actual hypersensitivity was not considered a viable option given the risks involved if a severe allergic reaction occurred with the test dose. Using IV opioid-based analgesia has harmful effects for both mother and the baby in addition to decreasing participation of mothers in the birthing process owing to its sedative properties...
