[Show abstract][Hide abstract] ABSTRACT: To compare morphine and tramadol in the treatment of postoperative pain (POP), using a system of Patient Controlled Analgesia (PCA).
Experimental design: Randomised comparative study on 88 patients, undergoing general major surgical operations (gastrectomy, colectomy and hemicolectomy). Patients: PCA i.v.: group M treated with morphine (at a dilution of 1 mg/ml) and group T with tramadol (at a dilution of 10 mg/ml). Loading dose: 0.05 mg/kg for the group treated with morphine and 0.5 mg/kg for the group treated with tramadol. Baseline infusion: 1.5 ml/h. Bolus on demand: 0.2 ml every 30 minutes. At T0, after 1 hour, 3 and 18 hours assessment of pain intensity, level of sedation, respiratory and cardiocirculatory parameters. After 18 hours assessment of the amount of drug administered, the number of boluses requested and given and any side effects. Statistical analysis: ANOVA test, Student "t", chi 2.
A statistically significant reduction in POP was found after 1 hour, 3 and 18 hours with no significant differences between the two groups. No statistically significant differences in cardiocirculatory or respiratory parameters or level of sedation were found. Few side effects were observed.
Tramadol determines pain relief similar to morphine, with the advantage that it does not lead to abuse, tolerance or addiction.

[Show abstract][Hide abstract] ABSTRACT: Latex allergy has become a real problem among both surgical staff (paramedics and physicians) and patients especially pediatric patients with urogenital malformations and spina bifida. Latex allergy is produced from both natural molecules which compose the substance produced from Hevea brasiliensis (rubber tree) and industrial additives contents in latex devices. Diagnosis of latex allergy may be carried out through a preoperative Prik-test. A characteristic of latex allergy reaction is the starting of symptoms (more than 15 minutes after allergen contact). Pathophysiology of latex allergy is the same of all allergic reactions; it is an antigen-antibody reaction and type I or II reaction may occur. There are a lot of devices that surgeons and anesthesists use in the operative theatre and that should not be used in presence of a patient with latex allergy. Guaranteed latex-free devices should always be present in store.
