Persistent pain following common outpatient surgeries in children: A multicenter study in Italy.

INTRODUCTION: The prevalence of persistent postsurgical pain in children is over 20% after major surgeries; however, data are scarce on the prevalence, character, and risk factors among children undergoing common ambulatory surgeries. The primary aim of this study was to evaluate the prevalence of persistent pain following pediatric ambulatory surgery at 1, 3, and 6 months. Secondary aims were to identify risk factors and characterize the pain and consequences of persistent postsurgical pain. METHODS: ASA I-II, ages 1 month to 16 years old, undergoing elective hypospadias repair, herniorraphy, orchiopexy, and orthopedic surgery were enrolled in a prospective, longitudinal, observational study at 3 pediatric centers in Italy. All patients received general plus regional anesthesia. Postoperative pain was evaluated using age appropriate pain scales at 1 and 3 hours. At 1, 3, and 6 months, pain scores were obtained and Parent's Postoperative Pain Measures (<8 yo) and Child Activity Limitations Interview (>8 yo) surveys were administered. RESULTS: About 350 patients completed the study. The prevalence of pain at 1, 3, and 6 months was 24% (84/350), 6.0% (21/350), and 4.0% (14/350), respectively. Inguinal herniorraphy patients experienced significantly higher pain at all 3-time points; 35.6%, 14.9%, and 9.2%. There was no significant association between mean pain scores >4 in PACU and persistent pain. Pain persisting at 6 months had neuropathic characteristics and frequently interfered with daily activities and sleep. CONCLUSION: Our data support the presence of persistent pain in pediatric patients after common surgeries. Most patients who developed persistent pain at 6 months had pain at 1 month. We recommend questioning at follow-up visit about persistent pain and functional impairment with follow-up until resolution.

Incidence of pain after craniotomy in children.

BACKGROUND: There is very few information regarding pain after craniotomy in children. OBJECTIVES: This multicentre observational study assessed the incidence of pain after major craniotomy in children. METHODS: After IRB approval, 213 infants and children who were <10 years old and undergoing major craniotomy were consecutively enrolled in nine Italian hospitals. Pain intensity, analgesic therapy, and adverse effects were evaluated on the first 2 days after surgery. Moderate to severe pain was defined as a median FLACC or NRS score ≥ 4 points. Severe pain was defined as a median FLACC or NRS score ≥ 7 points. RESULTS: Data of 206 children were included in the analysis. The overall postoperative median FLACC/NRS scores were 1 (IQR 0 to 2). Twenty-one children (16%) presented moderate to severe pain in the recovery room and 14 (6%) during the first and second day after surgery. Twenty-six children (19%) had severe pain in the recovery room and 4 (2%) during the first and second day after surgery. Rectal codeine was the most common weak opiod used. Remifentanil and morphine were the strong opioids widely used in PICU and in general wards, respectively. Longer procedures were associated with moderate to severe pain (OR 1.30; CI 1.07-1.57) or severe pain (OR 1.41; 1.09-1.84; P < 0.05). There were no significant associations between complications, pain intensity, and analgesic therapy. CONCLUSION: Children receiving multimodal analgesia experience little or no pain after major craniotomy. Longer surgical procedures correlate with an increased risk of having postoperative pain.

Emergence delirium in children: a comparison of sevoflurane and desflurane anesthesia using the Paediatric Anesthesia Emergence Delirium scale.

OBJECTIVES/AIM: This randomized control trial was designed to evaluate the incidence of emergence delirium (ED) in preschool children receiving sevoflurane or desflurane anesthesia combined with an effective caudal block. BACKGROUND: While ED has been described in children receiving sevoflurane or desflurane anesthesia, a direct comparison between the two agents using a validated ED assessment tool has not been reported previously. METHODS/MATERIALS: Two hundred and sixty preschool children scheduled for elective sub-umbilical surgery were randomized to receive sevoflurane or desflurane anesthesia combined with a caudal block. ED was defined as a Paediatric Anesthesia Emergence Delirium scale (PAED) ≥ 10 points. A delirium-specific score (ED I) was calculated from the first three items of the PAED score (eye contact, purposeful actions, awareness of the surroundings) and a nonspecific score (ED II) from the last two items on the PAED score (restlessness and inconsolability) to test the hypothesis that some items of the PAED scale may better reflect clinical ED than others. RESULTS: Thirty-one (25%) children in each group demonstrated ED after awakening with ED being of shorter duration in the desflurane group than the sevoflurane group. An ED I score of nine points had a sensitivity of 0.93 and a specificity of 0.94 for ED. An ED II score of five points had a sensitivity of 0.34 and specificity of 0.95 for ED. CONCLUSION: Sevoflurane and desflurane anesthesia were associated with similar incidences of ED in children undergoing sub-umbilical surgery and receiving effective regional anesthesia. High scores on the first three items of the PAED scale were highly correlated with ED. The items restlessness and inconsolability had lower sensitivity for the diagnosis of ED.

Caudal 0.2% ropivacaine is less effective during surgery than 0.2% levobupivacaine and 0.2% bupivacaine: a double-blind, randomized, controlled trial.

BACKGROUND: We hypothesized that without the analgesic effects of volatile anesthetics, caudal 0.20% ropivacaine would be less effective during surgical stimulation than 0.20% bupivacaine or 0.20% levobupivacaine. This trial was designed to examine whether the combination of a caudal block with 0.20% ropivacaine and i.v. anesthesia resulted in reduced analgesic efficacy during surgery compared with caudal 0.20% levobupivacaine or 0.20% bupivacaine in children. METHODS: Ninety ASA I-II children between 1 and 7 years old, scheduled for inguinal hernia repair or orchidopexy under propofol anesthesia were randomized to receive a caudal block with 1 ml x kg(-1) of 0.2% bupivacaine, 0.2% ropivacaine or 0.2% levobupivacaine. The primary outcome measure of the study was the clinical efficacy of the caudal block during surgery. Secondary outcome measures were postoperative pain relief and residual motor blockade. RESULTS: Four children were excluded and 86 were analyzed. The proportion of children with effective caudal block during surgery was significantly higher in children receiving levobupivacaine (26/28) or bupivacaine (27/29) compared with patients receiving ropivacaine (21/29) (P = 0.03). There were no significant differences among groups in the analgesic onset time (P = 0.1), incidence of residual motor blockade (P = 0.4), number of patients requiring analgesia after operation or in the time from caudal injection to the first administration of analgesic medication (P = 0.3). CONCLUSIONS: Combined with propofol anesthesia, 0.2% levobupivacaine and 0.2% bupivacaine are more effective than 0.2% ropivacaine for caudal use in children undergoing inguinal hernia repair or orchidopexy.

Consideraciones prácticas para el desarrollo de programas de analgesia postoperatoria / Implementation practical aspects of postoperative pain programs

Los programas de analgesia postoperatoria que cuentan con sistemas de registro de dolor, sedación y efectos adversos de los fármacos, utilizados junto al resto de los controles sistemáticos que se realizan en todos los pacientes, mejoran la calidad de atención del postoperatorio. La puesta en práctica de normativas generales implica la adecuación de las normas a la realidad de cada institución, la capacitación y el entrenamiento de todo el personal, la transformación de conductas y hábitos contrarios a las normas, la selección cuidadosa de pacientes y sectores de internación y la evaluación periódica de los resultados. Es claro que la solución a los problemas del manejo del dolor postoperatorio no se encuentran en el desarrollo de nuevas técnicas, sino en la organización y explotación de los recursos existentes. El desarrollo del nuevo proyecto no es dependiente de cuánto se tiene, sino de cuánto se puede hacer con lo que se tiene. El objetivo del presente trabajo es revisar, en base a la experiencia acumulada en nuestros hospitales, los aspectos prácticos de la puesta en funcionamiento de programas de analgesia postoperatoria en el ámbito hospitalario.
