Adequate Sedation (adequate + sedation)
Selected AbstractsThree cases of PICU sedation with isoflurane delivered by the ,AnaConDaŽ'PEDIATRIC ANESTHESIA, Issue 10 2005PETER V. SACKEY MD Summary Prolonged sedation in the pediatric intensive care unit may be difficult because of tolerance, drug dependence and withdrawal, drug interactions and unwanted drug effects. We present three patients sedated with isoflurane via the Anesthetic Conserving Device, AnaConDaŽ. AnaConDaŽ is a modified heat and moisture exchanger that allows evaporation and delivery of inhalational anesthetics without an anesthesia machine, vaporizer or adapted ventilator. Two patients with abdominal complications and prolonged sedation for mechanical ventilation were converted to isoflurane sedation for several days. The third patient with refractory status epilepticus received isoflurane to treat epileptiform electroencephalogram activity. Patients weighing 40 and 30 kg were treated with AnaConDaŽ placed at the Y-piece, while the patient weighing 20 kg was treated with AnaConDaŽ in the inspiratory limb of the respiratory circuit. Adequate sedation was achieved with endtidal isoflurane concentration of 0.3,0.4%, while antiepileptic effect was achieved at a higher dose, 0.9%. Intravenous sedatives could be reduced or discontinued during isoflurane sedation. Inhaled sedation of isoflurane with AnaConDaŽ was effective in these patients. It may provide an alternative in difficult cases needing prolonged sedation and should be evaluated further.

ALMGREN Background: Awareness about adequate sedation in mechanically ventilated patients has increased in recent years. The use of a sedation scale to continually evaluate the patient's response to sedation may promote earlier extubation and may subsequently have a positive effect on the length of stay in the intensive care unit (ICU). The Richmond Agitation-Sedation Scale (RASS) provides 10 well-defined levels divided into two different segments, including criteria for levels of sedation and agitation. Previous studies of the RASS have shown it to have strong reliability and validity. The aim of this study was to translate the RASS into Swedish and to test the inter-rater reliability of the scale in a Swedish ICU. Methods: A translation of the RASS from English into Swedish was carried out, including back-translation, critical review and pilot testing. The inter-rater reliability testing was conducted in a general ICU at a university hospital in the south of Sweden, including 15 patients mechanically ventilated and sedated. Forty in-pair assessments using the Swedish version of the RASS were performed and the inter-rater reliability was tested using weighted , statistics (linear weighting). Result: The translation of the RASS was successful and the Swedish version was found to be satisfactory and applicable in the ICU. When tested for inter-rater reliability, the weighed , value was 0.86. Conclusion: This study indicates that the Swedish version of the RASS is applicable with good inter-rater reliability, suggesting that the RASS can be useful for sedation assessment of patients mechanically ventilated in Swedish general ICUs. [source] Titrated propofol induction vs. continuous infusion in children undergoing magnetic resonance imagingACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2010J. E. CHO Background: Propofol is the popular intravenous (i.v.) anaesthetic for paediatric sedation because of its rapid onset and recovery. We compared the efficacy and safety of a single dose and conventional infusion of propofol for sedation in children who underwent magnetic resonance imaging (MRI). Methods: This was a double-blind, randomized-controlled study. One hundred and sixty children were assigned to group I (single dose) or II (infusion). Sedation was induced with i.v. propofol 2 mg/kg, and supplemental doses of propofol 0.5 mg/kg were administered until adequate sedation was achieved. After the induction of sedation, we treated patients with a continuous infusion of normal saline at a rate of 0.3 ml/kg/h in group I and the same volume of propofol in group II. In case of inadequate sedation, additional propofol 0.5 mg/kg was administered and the infusion rate was increased by 0.05 ml/kg/h. Induction time, sedation time, recovery time, additional sedation and adverse events were recorded. Results: Recovery time was significantly shorter in group I compared with group II [0 (0,3) vs. 1 (0,3), respectively, P<0.001]. Group I (single dose) had significantly more patients with recovery time 0 compared with group II (infusion) (65/80 vs. 36/80, respectively, P<0.001). Induction and sedation times were not significantly different between groups. There was no significant difference in the frequency of additional sedation and adverse events between groups. Conclusion: A single dose of propofol without a continuous infusion can provide appropriate sedation in children undergoing MRI for <30 min. [source] The efficacy of orally dosed ketamine and ketamine/medetomidine compared with intramuscular ketamine in rhesus macaques (Macaca mulatta) and the effects of dosing route on haematological stress markersJOURNAL OF MEDICAL PRIMATOLOGY, Issue 3 2008Andrew N Winterborn Abstract Background, This study compared the efficacy of two orally-dosed (PO) anaesthetic regimens for chemical immobilization in rhesus macaques (Macaca mulatta), versus the standard protocol of intramuscular (TM) ketamine. In addition, the effects of dosing route on haematological stress markers were evaluated. Methods, Testing was conducted on 18 chronically housed animals. Animals were trained to accept oral dosing and then randomly assigned to one of three drug regimens: (1) ketamine IM, (2) ketamine PO, (3) Ketamine/medetomidine PO. Sedation levels for each regimen were evaluated. Results, Oral dosing alone was not sufficient to achieve a plane of sedation that allowed for safe handling. Serum cortisol and glucose levels were unchanged across groups, although differences were observed in the leukogram profiles. Conclusion, The oral dosages used in this study fell short in providing adequate sedation for safe handling for routine veterinary procedures. Leukogram profiles indicated that orally dosed animals experienced a higher level of stress. [source] Sedation with ketamine and low-dose midazolam for short-term procedures requiring pharyngeal manipulation in young childrenPEDIATRIC ANESTHESIA, Issue 1 2008HELENA NOVAK MD Summary Background:, Pediatric intestinal biopsy procedures including considerable transpharyngeal manipulation of a wire-guided metal capsule require adequate sedation or anesthesia. This retrospective cohort study was designed to evaluate intravenous sedation with ketamine and low-dose midazolam in young children undergoing these procedures before and also after discharge from the hospital. Methods:, A total of 244 biopsy procedures in 217 children under the age of 16 years were evaluated. All anesthesia records were reviewed according to a defined study protocol and in 145 cases the parents were also interviewed by telephone to obtain further information on possible adverse effects before and after discharge. Results:, Ketamine and low-dose midazolam were carefully titrated by an experienced anesthesia team at an approximate dose ratio of 40 : 1 (total doses 2.3 and 0.05 mgˇkg,1) in continuously monitored spontaneously breathing children. Possibly associated problems before discharge were salivation (5.7%), vomiting (4.9%), oxygen desaturation (3.3%), laryngospasm (2.5%) and rash (1.2%) according to the patient records and blurred vision (27%), nausea and vomiting (19%), vertigo (13%) and hallucinations or nightmares (3.5%) according to telephone interviews. Few, mild and transient problems remained after discharge from the hospital. Conclusions:, Careful titration of ketamine and low-dose midazolam provides adequate sedation for nonsurgical pediatric short-term procedures also requiring considerable pharyngeal manipulation, particularly considering the low number of serious airway problems such as laryngospasm. The high incidence of late postoperative problems suggests that prospective studies should be designed for long-term follow-up of young children subjected to sedation or anesthesia. [source] Managing sedation withdrawal in children who undergo prolonged PICU admission after discharge to the wardPEDIATRIC ANESTHESIA, Issue 4 2004M. Cunliffe MBBS Summary Children who undergo a prolonged stay within the intensive care unit require adequate sedation and analgesia. During the recovery phase there will need to be a period of sedation withdrawal to prevent occurrence of an abstinence syndrome. We present a strategy developed within our hospital for managing this process which uses the resource of the Pain Service, along with guidelines to help prevent the development of withdrawal, and a plan for managing any signs of abstinence which occur.
