RESUMO
INTRODUCTION: Diagnostic delay in Hirschsprung disease is uncommon. Different definitions have been proposed but that of a diagnosis achieved after 12 months of age seems to be the most reliable and resorted to. Some authors reported a worse outcome in case of delay. Our study aims at providing the most relevant features of a series of patients who received a delayed diagnosis of Hirschsprung disease. MATERIALS AND METHODS: All consecutive patients admitted to our Center with a delayed diagnosis of Hirschsprung diseases between January 2017 and July 2023 have been retrospectively enrolled. Demographic data, phenotype, genotype, surgical complications, and outcome were assessed and compared to those of literature. A number of variables were also compared to those of a series of patients admitted during the same study period without a delayed diagnosis. RESULTS: A total of 45 patients were included (16.4% out of a series of 346 patients with data regarding age at diagnosis). Male to female ratio was 3.1:1. Median age at diagnosis was 41 months with a wide variation (range between 17 months and 58 years). All patients but 2 suffered from classic rectosigmoid aganglionosis. Normal meconium passage (58%) was reported in a significantly higher number of patients compared to what observed in a series without diagnostic delay (p = 0.0140). All other variables (associated anomalies, preoperative enterocolitis, complications, and functional outcome) proved not to have statistically significant differences compared to a series of patients without a diagnostic delay. CONCLUSIONS: The results of our study underline that a significant percentage of patients are basically missed in the neonatal period mostly due to mild symptoms. Overall outcome does not differ from that of patients without diagnostic delay. Nonetheless, we underline the importance of a throughout investigation of all patients with meconium delay/failure and that of adopting a low threshold for performing rectal suction biopsies in constipated children to avoid misdiagnosis to serve the best for our patients.

BACKGROUND: Anal fistula is a common acquired anorectal disorder in children. Treatment methods that have been used are associated with inconsistent results and possible serious complications. In 2011 a minimally invasive approach, video-assisted anal fistula treatment (VAAFT) was described for adult patients. The aim of the present study was to assess the first series of pediatric patients treated with VAAFT. METHODS: All patients who underwent VAAFT between August 2013 and May 2015 were included. Demographics, clinical features, preoperative imaging, surgical details, outcome, and medium-term data were prospectively collected for each patient. RESULTS: Thirteen procedures were performed in nine patients. The male to female ratio was 8:1, and the median age was 9.6 years. Five fistulas were idiopathic, three iatrogenic, and one associated with Crohn's disease. Eight complete VAAFT procedures were performed. The remaining five procedures were either fistuloscopy and cutting seton placement or fistuloscopy and electrocoagulation, both without mucosal sleeve. The median length of surgery was 41 min. The median hospital stay was 24 h, and the median length of follow-up was 10 months. Resolution of the fistula was observed in all patients who underwent a complete VAAFT. In four out of five patients who underwent an incomplete procedure (without mucosal sleeve), the fistula recurred. No incontinence or soiling was reported in the medium term. CONCLUSIONS: VAAFT proved to be feasible and safe in children. It also proved to be versatile as it could be applied to fistulas of different etiologies. The key to success seems to be an adequate mucosal sleeve. Older children and adolescents benefit most from VAAFT which is a valid alternative to available surgical procedures.

BACKGROUND/PURPOSE: Aim of this study was to present a series of neonates and ex-preterm babies who underwent inguinal hernia repair focusing on complications and possible indication to perform routine contralateral groin exploration. METHODS: This is a retrospective study of a series of consecutive patients weighing less than 5 kg who underwent inguinal hernia repair between January 2007 and December 2012. Only the affected side was treated. Patients have been routinely followed up postoperatively. We resorted to available outpatients' charts and admission notes to record demographic data, surgical details, complications and the occurrence of metachronous hernias. A questionnaire was administered to all patients' relatives to confirm the long-term outcome. RESULTS: One hundred fifty-four patients were operated for a total of 184 herniotomies (88 right sided, 36 left sided and 30 bilateral). Median length of follow-up was 42 months (range 6 months-7.5 years). Thirteen patients (13/124 = 10.5 %) developed metachronous hernia that proved to be significantly more frequent in patients weighing less than 1,500 g at birth (p < 0.05). We observed 10 % of complications, including 2.7 % testicular atrophy and 4.5 % recurrence. Atrophy proved to occur more frequently in patients who experienced preoperative incarceration (p < 0.05). No other risk factors were identified. CONCLUSIONS: The results of our series demonstrated that, though technically demanding, herniotomy in the neonate and ex-preterm is associated with a relatively low incidence of complications. Based on our results and in accordance with literature data, we do not advocate routine contralateral exploration in case of unilateral hernia but surgery to be performed only on the symptomatic side, as soon as possible after initial diagnosis. Very low birth weight patients should be followed with care in the early postoperative period due to the higher likelihood of developing a metachronous hernia.

BACKGROUND: Inflammatory Bowel Diseases (IBD) are known to occur in association with Hirschsprung disease (HSCR). Most of cases are represented by Crohn Disease (CD) occurring in patients with Total Colonic Aganglionosis (TCSA) with an estimated prevalence of around 2%. Based on these considerations and on a number of provisional data belonging to our Center for Digestive Diseases, we developed a unicentric cross-sectional observational study aimed at describing phenotype, genotype, pathology and metagenomics of all patients with TCSA and Crohn-like lesions. RESULTS: Out of a series of 62 eligible TCSA patients, 48 fulfilled inclusion criteria and were enrolled in the study. Ten patients did not complete the study due to non-compliance or withdrawal of consent and were subsequently dropped out. A total of 38 patients completed the study. All patients were tested for chronic intestinal inflammation by a combination of fecal calprotectine (FC) or occult fecal blood (OFB) and underwent fecal metagenomics. Nineteen (50%) tested positive for FC, OFB, or both and subsequently underwent retrograde ileoscopy. Fourteen patients (36.8%) presented Crohn-like lesions, occurring after a median of 11.5 years after surgery (range 8 months - 21.5 years). No statistically significant differences regarding demographic, phenotype and genotype were observed comparing patients with and without lesions, except for need for blood transfusion that was more frequent in those with lesions. Faecal microbiome of patients with lesions (not that of caregivers) was less biodiverse and characterized by a reduction of Bacteroidetes, and an overabundance of Proteobacteria. FC tested negative in 3/14 patients with lesions (21%). CONCLUSIONS: Our study demonstrated an impressive 10-folds higher incidence of chronic inflammation in TCSA. Up to 50% of patients may develop IBD-like lesions postoperatively. Nonetheless, we failed in identifying specific risk factors to be used to implement prevention strategies. Based on the results of our study, we suggest screening all TCSA patients with retrograde ileoscopy regardless of FC/OFB values. The frequency of endoscopic assessments and the role of FC/OFB screening in prompting endoscopy is yet to be determined.

Activation of the oxidative burst and failure of CD4(+) CD25(+) cell regulation have been implicated in idiopathic nephrotic syndrome (iNS). The intimate mechanism is, however, unknown and requires specifically focused studies. We investigated reactive oxygen species (ROS) generation [di-chlorofluorescein-diacetate (DCFDA)] fluorescence assay and the regulatory adenosine 5'-triphosphate (ATP) pathways in the blood of 41 children with iNS, utilizing several agonists and antagonists of nucleotide/nucleoside receptors, including the addition of soluble apyrase. The CD4(+) CD25(+) CD39(+) /CD73(+) expression was determined in vivo in parallel during disease activity. Overall, we found that the percentage of CD39(+) CD4(+) CD25(+) was reduced markedly in iNS by 80% (3·43±0·04% versus 13·14±0·07% of total lymphocytes, P<0·001). In these patients, reactive oxygen species (ROS) generation by polymorphonuclear neutrophils (PMN) at rest was a function of apyrase (CD39) expressed by CD4(+) CD25(+) , with higher rates in patients with very low CD39(+) CD4(+) CD25(+) levels (<7·5%). Addition of apyrase reduced ROS generation by 40% in both iNS and controls and was mainly effective in patients. The quota of ROS surviving ATP elimination was higher still in iNS. In vitro studies to limit ROS generation with adenosine analogues (2'-chloroadenosine and 5'-N-ethylcarboxamidoadenosine) produced minor effects. At variance, antagonizing ATP efflux with carbenoxolone or by antagonizing ATP effects (Brilliant Blue G, KN62 and A437089) reduced ROS generation comparable to apyrase. These results confirm a key role of ATP in the regulation of innate immunity and minimize the effect of adenosine. Decreased CD39(+) CD4(+) CD25(+) expression in iNS highlights an impairment of ATP degradation in this pathology. However, high ROS surviving ATP consumption implies a major role of other regulatory pathways.

Chronic intestinal pseudo-obstruction (CIPO) can occur as a consequence of neuropathies including diffuse Intestinal Neuronal Dysplasia (IND), a relatively rare enteric nervous system (ENS) abnormality. Although various authors reported of diffuse IND associated either with intestinal malrotation or megacystis, the co-existence of these three entities in the same patient has never been described before. The aim of this paper is to report for the first time in literature a series of patient with such association, focusing on one who carries a de novo duplication of chromosome 12, suggesting a new syndromic association (megacolon, megacystis, malrotation).

The mechanism responsible for proteinuria in non-genetic idiopathic nephrotic syndrome (iNS) is unknown. Animal models suggest an effect of free radicals on podocytes, and indirect evidence in humans confirm this implication. We determined the oxidative burst by blood CD15+ polymorphonucleates (PMN) utilizing the 5-(and-6)-carboxy-2',7'-dichlorofluorescin diacetate (DCF-DA) fluorescence assay in 38 children with iNS. Results were compared with PMN from normal subjects and patients with renal pathologies considered traditionally to be models of oxidative stress [six anti-neutrophil cytoplasmic autoantibody (ANCA) vasculitis, seven post-infectious glomerulonephritis]. Radicals of oxygen (ROS) production was finally determined in a patient with immunodeficiency, polyendocrinopathy, enteropathy X-linked (IPEX) and in seven iNS children after treatment with Rituximab. Results demonstrated a 10-fold increase of ROS production by resting PMN in iNS compared to normal PMN. When PMN were separated from other cells, ROS increased significantly in all conditions while a near-normal production was restored by adding autologous cells and/or supernatants in controls, vasculitis and post-infectious glomerulonephritis but not in iNS. Results indicated that the oxidative burst was regulated by soluble factors and that this regulatory circuit was altered in iNS. PMN obtained from a child with IPEX produced 100 times more ROS during exacerbation of clinical symptoms and restored to a near normal-level in remission. Rituximab decreased ROS production by 60%. In conclusion, our study shows that oxidant production is increased in iNS for an imbalance between PMN and other blood cells. Regulatory T cells (Tregs) and CD20 are probably involved in this regulation. Overall, our observations reinforce the concept that oxidants deriving from PMN are implicated in iNS.

BACKGROUND: The role of surgery is debated for children with gastroesophageal reflux disease (GERD), particularly when they show atypical symptoms. This study was designed to evaluate the safety and outcome of laparoscopic Nissen-Rossetti fundoplication performed in a selected population of children with gastroesophageal reflux and atypical supraesophageal symptoms. METHODS: This prospective study included 595 patients younger than 14 years with GERD who reported recurrent respiratory symptoms and had no benefit from standard medical treatment. Surgery was performed for 48 patients with anatomic anomalies, life-threatening events, or respiratory complications after ineffective medical treatment. The subjective and objective outcomes were evaluated. RESULTS: No major intraoperative complications were experienced, and there was no recurrence of gastroesophageal reflux during a postoperative follow-up period of 12 months. The parents' final subjective evaluation of the outcomes 12 months after surgery was positive in 44 cases and negative in 4 cases. CONCLUSIONS: Children with difficult-to-treat chronic respiratory symptoms must be evaluated for GERD, even if the need for surgery is low (8%), because complete eradication of reflux is mandatory. Radical treatment of GERD allows the pulmonologist to perform correct respiratory treatment and to prevent the development chronic and life-threatening complications.

BACKGROUND: Gallbladder stones are a well-known and widely studied problem in children. Hematological disorders are the most common diseases that can cause cholelithiasis. However, in the last few years, the proportion of children with idiopathic cholelithiasis has increased 50%. Herein, we present a prospective study on laparoscopic cholecystectomy in a selected group of patients aged < 10 years. METHODS: Fifty-eight patients aged < 10 years underwent laparoscopic cholecystectomy for stones in the period 1992-99. The female/male ratio was 1.5, the mean age was 8 years (range, 2-10), and the mean weight was 30 kg. In all patients, parenteral nutrition, fasting state, and prolonged use of antibiotics had been suspended for > or = 6 months, and conservative treatment had been tried for > or = 12 months in the absence of symptoms of stone migration. All the patients were followed up after surgery: clinically at 1,6,12, and 36 months and by ultrasound at 1, 12, and 36 months. Liver function and hematological tests were performed in case of symptoms or if hemolytic disorders were the cause of stones. RESULTS: The mean operative time was 63 min (range, 30-120) in children undergoing cholecystectomy alone and 150 min in children undergoing associated splenectomy. There were no major complications or reoperations. Minor complications included bleeding from accessory cystic artery (n = 3) and insufflation of the omentum (n = 2). One case was converted to an open procedure due to technical problems. All the children were followed up and no complications were observed. CONCLUSION: We consider the laparoscopic approach the gold standard for cholecystectomy in children. This procedure does not have a complication rate any higher than open cholecystectomy, and patient follow-up is as good as that of open surgery. Previous abdominal surgery is not a contraindication to laparoscopy.

INTRODUCTION: During the past three decades laparoscopy has significantly improved. As fundoplication extensively benefits by the great advantages of the minimally invasive approach, many surgeons chose laparoscopic fundoplication for the treatment of gastroesophageal reflux in adults and children as well. Pneumothorax, cardiovascular collapse, hypoxia, and hypercarbia are some of the anesthesiologist's principal fears during carbon dioxide insufflation. Thus, monitoring cardiovascular and respiratory status is mandatory to early detect any complication and to maintain a proper balance during pneumoperitoneum. MATERIALS AND METHODS: At Gaslini Children's Hospital we performed a prospective nonrandomized study aimed at describing the main cardiorespiratory changes produced by pneumoperitoneum in 33 pediatric patients operated on by laparoscopic fundoplication between January 2000 and June 2001. Patients were divided into two groups; namely, group A and group B. Group A included 14 patients with chronic respiratory symptoms, and group B included 19 children who preoperatively mainly emphasized gastrointestinal symptoms. We monitored intraoperative cardiorespiratory status, timed length of surgery, and described intraoperative complications. RESULTS: No significant cardiovascular changes occurred during carbon dioxide insufflation. Partial oxygen saturation remained still in all the patients. End tidal CO2, meanly higher in group A children, increased in all the patients after pneumoperitoneum creation, but never exceeded 45 mmHg. Similarly, peak inspiratory pressure increased in all the patients, but was always maintained within acceptable values. Finally, group B patients required a harder and slower surgery, whose length seems to be negatively influenced by age. No intraoperative complication occurred. CONCLUSIONS: Carbon dioxide insufflation does not impair cardiovascular function, if intraabdominal pressure is maintained lower than 10 mmHg nor does it interfere with gas exchanges. Pneumoperitoneum slightly reduces ventilatory function, mainly in respiratory patients with various degrees of underlying bronchopulmonary impairments, but this effect is easily correctable. Thus, laparoscopic fundoplication is feasible and safe in both respiratory and gastroenterological patients, although surgery is easier and faster if periesophagitis is less evident.

BACKGROUND: The laparoscopic approach has become increasingly popular for fundoplication over the last few years; however many surgeons are skeptical about its real advantages. METHODS: We conducted a prospective comparative study of children operated on for gastroesophageal reflux (GER). Exclusion criteria included age <1 YEAR AND >14 years, previous surgery on the esophagus or stomach, and neurologic impairment. We compared two groups of patients who met the same inclusion/exclusion criteria. One group was treated via a laparotomic approach between January 1993 and December 1997; the other was treated via a laparoscopic approach between September 1998 and December 2000. A 360 degrees wrap was performed in each group. RESULTS: Group 1 (laparotomic approach) included 17 patients; mean operative time was 100 min and postoperative time was 7 days. Group 2 comprised 49 children operated on via a laparoscopic approach; mean operative time was 78 min and postoperative time was 48 hours. No major complications were encountered in either group. In postoperative period, two patients in group 1 had complications. One had a prolonged bout of gastroplegia, which required nasogastric drainage, and then recovered spontaneously after 20 days; the other had stenosis of the wrap, which required dilation. No relapses occurred during a follow-up of 6 months. Long-term follow-up data are not presented. Comparative analysis of the short-term functional results indicated that there were no differences between the two groups. CONCLUSION: This study confirms that the minimally invasive approach is safe and effective for the treatment of primary gastroesophageal reflux disease in children.

BACKGROUND: Esophageal achalasia is not a frequent disorder in children and different treatments have been proposed during past decades. This study reviews the results of the laparoscopic Heller-Dor procedure performed in pediatric patients in two different surgical units. METHODS: We included the patients aged <14 years with a minimum follow-up of 6 months operated on in the period 1994-2001. A single longitudinal anterior esophageal myotomy (Heller) and a 180 degrees anterior gastropexy (Dor) were laparoscopically performed. The patients were checked to detect intra- or postoperative complications and recurrence. RESULTS: Twenty children were operated on. Mean follow-up was 45 months (range 6-102). Postoperative clinical score was Visick 1 in 15 cases and Visick 2 in five. CONCLUSIONS: As complication and recurrence rates are very low we consider modified Heller myotomy and Dor gastropexy through a laparoscopic approach our first choice to treat esophageal achalasia in the pediatric population.

We selected a paediatric population with a high risk of nosocomial infection formed by 116 newborns (42.8%) and 155 not newborns (57.2%) admitted into the ICU of the Giannina Gaslini Institute during the period 1-1-1992-30-9-1992; we compared it with a reference paediatric population studied in the same department during the period 1-1-1987-30-6-1988 formed by 310 newborns (44.3%) and 391 not newborns (55.7%). The purpose of this study is to evaluate the possible change in the incidence of colonizations and ICU specific nosocomial infections, the possible increase of nosocomial infections by multiresistant Staphylococci and the appearance of new multiresistant germs. The two populations obviously present similar factors of high risk of nosocomial infection (naso-tracheal intubation, mechanical ventilation, total parenteral nutrition, surgical procedures, thoracic and/or abdominal prothesis, etc.). The obtained data have been examined with the Chi-square method. The incidence of colonizations remained unchanged while we noted a significant increase (10.3% compared to 4.9%-p > 0.0014) of the "ICU" specific nosocomial infections; the increase regarded mainly the neonatal population (18.9% compared to 7%-p > 0.00001). Significant increase of the nosocomial infections by multiresistant Staphylococcus (Staphylococcus haemolyticus) with in vitro and in vivo resistance to teicoplanin. Furthermore, presence in the performed study of multiresistant gram negative germs.

AIM: This paper describes our experience with minimally invasive surgery and underlines its increasingly important role in the treatment of pediatric patients. METHODS: The study included all those patients undergoing a minimally invasive surgical procedure between January 2006 and March 2012. Patient demographics, type of operation (classified according to disease and anatomic site), complications, and length of hospital stay (LOS) were recorded. RESULTS: Out of 12,596 surgeries, 1803 (14.3%) minimally invasive procedures were performed: Soave-Georgeson endorectal colon pull-through for Hirschsprung's disease (N.=82); colectomy for chronic inflammatory bowel disease (N.=37); ileal J-pouch ano-rectal Knight-Griffen anastomosis in colectomized patients with chronic ulcerative colitis (N.=35); Nissen fundoplication for gastroesophageal reflux disease (N.=148); cholecystectomy (N.=68); appendectomy (N.=341); laparoscopic or thoracoscopic tumor resection or biopsy (N.=90); reconstruction of the renal pelvi and ureters (N.=11); and Nuss thoracoplasty for pectus excavatum (N.=237). The median age was 3 years; the median LOS was 3 days; the complications rate was 0.9% (N.=18). CONCLUSION: According to our experience, minimally invasive surgery is a safe and efficacious alternative to conventional surgery (in terms of complications) also in children. It was associated with shorter LOS and improved quality of life, with less pain and better aesthetic results. It has become the preferred surgical treatment option by parents.

BACKGROUND: The preoperative assessment involves the process of evaluating the patient's clinical condition, which is intended to define the physical status classification, eligibility for anesthesia and the risks associated with it, thus providing elements to select the most appropriate and individualized anesthetic plan. The aim of this recommendation was provide a framework reference for the preoperative evaluation assessment of pediatric patients undergoing elective surgery or diagnostic/therapeutic procedures. METHODS: We obtained evidence concerning pediatric preoperative evaluation from a systematic search of the electronic databases MEDLINE and Embase between January 1998 and February 2012. We used the format developed by the Italian Center for Evaluation of the Effectiveness of Health Care's scoring system for assessing the level of evidence and strength of recommendations. RESULTS: We produce a set of consensus guidelines on the preoperative assessment and on the request for preoperative tests. A review of the existing literature supporting these recommendations is provided. In reaching consensus, emphasis was placed on the level of evidence, clinical relevance and the risk/benefit ratio. CONCLUSION: Preoperative evaluation is mandatory before any diagnostic or therapeutic procedure that requires the use of anesthesia or sedation. The systematic prescription of complementary tests in children should be abandoned, and replaced by a selective and rational prescription, based on the patient history and clinical examination performed during the preoperative evaluation.

AIM: The aim of this paper was to provide the main clinical features, surgical details, and long term outcome of patients with gastroschisis and omphalocele operated on at Giannina Gaslini Institute between 1976 and 2009. METHODS: All patients who were operated on between 1976 and 2009 for omphalocele or gastroschisis were included. Detailed informations regarding demographics, maternal history, type of delivery, associated anomalies, surgical details, complications, morbidity and mortality were collected. RESULTS: Sixty-one patients were included. Type of delivery did not interfere with outcome. Although patients with omphalocele had higher incidence of associated anomalies with their obvious impact on survival and quality of life, they showed a quicker recovery from surgery. Mortality rate was around 5%. Long-term outcome was available in 18 of them and proved to be satisfactory in all although almost 70% of them complained some gastrointestinal issues. CONCLUSION: Gastroschisis and Omphalocele showed improving survival and outcome during the last decades. Caesarean section proved not to confer advantages over vaginal delivery. Associated anomalies have the highest impact on survival being cardiac malformation the most significant risk factors. Although overall outcome is good in the majority of the patients, gastrointestinal and cosmetic issues seem to have a significant impact on quality of life and overall patients' perspectives.

AIM: Pectus excavatum is the commonest thoracic congenital malformation, but its treatment remains not well known. The authors present the results of the mini-invasive repair at G. Gaslini Institute of Genoa, Italy. METHODS: Nuss mini-invasive repair avoids anterior scars. The correction is achieved by the introduction under thoracoscopy of a retrosternal curve bar that is rotated by 180 degrees . Postoperatory pain is managed by an epidural catheter. In all the operated patients we evaluated the clinical pre-operatory parameters (spirometric, radiological and cardiological data), the surgical details and the results. RESULTS: Fifty patients were operated, 43 of them males, ranging from 7 and 22 years of age, with an average of 17 years of age. Only 8 of them were asymptomatic and required surgery for psychological reasons. The 74% presented some stress dyspnea. Some impairment in spirometric parameters were observed in 28% and mitral valve prolapse in 30%. The only significant intra-operative complication was a bleeding from a thoracic wall vessel that required a left emergency minimal thoracotomy. Postoperative complications were: 2 pneumothorax (drained for 24 hours), 2 transitory pulmonary atelectasis, 1 hemothorax in a patient with coagulation deficit, 3 wound problems (1 infection and 2 hematomas). The esthetical score after surgery, according to the patients, was 9.15 on average, in a scale from 1 to 10. None rated less than 7. The pain score with the same scale was rated 6.8 on average. CONCLUSION: The Nuss technique is safe and guarantees very satisfactory esthetical results.

OBJECTIVE: To evaluate the effectiveness of a single bolus of epidural (ED) clonidine (C) associated with intrathecal morphine (M) on postoperative analgesia after cesarean section (CS). DESIGN: Prospective double-blind randomized study. SETTING: Obstetric department. PATIENTS: Fourty patients ASA 1-2 submitted to combined spinal-epidural block (CSE) for CS. INTERVENTIONS: A needle through needle set for CSE was used. The intrathecal block was induced with 2.7-3 ml of isobaric 0.5% bupivacaine (B) and 250 micrograms of M. After ED test with 0.5% B, a single bolus of C 150 micrograms in NS 10 ml (group C, n 20) or NS 10 ml as placebo (group P, n 20) was given through the ED catheter. METHODS: The observation for 36 hours evaluated analgesia (VAS until the first dose of additional analgesic, total amount of analgesic and time of first analgesic request) and side effects (variations of arterial pressure and heart rate, motor block, sedation, nausea, vomiting, itching, respiratory depression). Groups were statistically compared. RESULTS: In group C lower analgesic request (significantly between 12th and 18th hour) and significant delay of first request (22.5 +/- 4.1 h) were registered. VAS showed significant trend to opposite sign variations (downwards in group C, upwards in group P) at 1, 2 and 12 hours. In group C lower sistolic arterial pressure at 1 and 4 hours, denser motor block at 2 and 4 hours and mild sedation were observed. CONCLUSIONS: A single ED bolus of C 150 micrograms after CS significantly enhances and prolongs the analgesic effect of M 250 micrograms without important side effects.
