BACKGROUND: Children often require relief of pain and anxiety when undergoing painful procedures. The purpose of this study is to evaluate the effectiveness and safety of painful pediatric procedures performed by pediatric intensivist, using the combination of intravenous ketamine and midazolam for sedation and analgesia. METHODS: The records of the patients who received intravenous ketamine-midazolam combination for painful procedures in the pediatric sedation unit of a university hospital over a 3 year period were retrospectively reviewed to determine indications, dosing, assessment of the level of sedation, adverse events, and recovery time for each procedural sedation and analgesia. RESULTS: A total of 227 children aged 4 months to 18 years were admitted to the pediatric sedation unit for a total of 356 procedures. The indications for procedural sedation and analgesia included bone marrow aspiration or biopsy (50.8%), central venous catheter insertion (27%), and others (22%). A total of 46 adverse events (12.9%) were observed. These adverse events included SpO2 below 85% without apnea (n = 14), apnea (n = 3), transient stridor (n = 2), hypertension and tachycardia (n = 8), hypersalivation (n = 6), vomiting (n = 5), hallucinatory emergence reaction (n = 4), and rash (n = 4). There were no adverse outcomes attributable to ketamine and midazolam combination. CONCLUSION: Skilled pediatric intensivists can safely and effectively administer ketamine and midazolam to facilitate painful procedures outside the operating room setting. 相似文献

Summary. This report evaluates the haemostatic efficacy of recombinant factor VIIa (rFVIIa) and activated prothrombin complex concentrate (APCC) in patients with haemophilia and high responding inhibitors who underwent major and minor surgery. Data pertaining to surgeries from 2001 to 2009 at a single centre were retrospectively analysed. During this period, 53 surgical procedures were performed in 30 haemophiliacs with high responding inhibitors. Mean age was 16.2 ± 9.4 years. Eleven major surgeries in 4 patients, 41 radioisotope synovectomies (RS) and one circumcision classified as minor surgery in 28 patients were performed. Among the major surgery procedures, four were treated with rFVIIa, five with APCC and two with sequential use of APCC and rFVIIa. We used rFVIIa at the dosage of 80–120 μg kg?1 every 2 h and APCC 100 IU kg?1 every 12 h for the major surgery. When performing RS, we used rFVIIa in 18 patients with 26 target joints and APCC in 9 patients with 15 target joints. Three consecutive doses of rFVIIa (90 μg kg?1) were used at 2‐h intervals followed by additional three doses at 6‐h intervals. The initial dose of APCC was 75 IU kg?1 followed by a second and third dose of 50 IU kg?1 at 12‐h intervals. APCC and rFVIIa demonstrated excellent efficacy in our major and minor surgical interventions [100% (22/22) and 94% (31/33), respectively]. We had only two bleeding complications with rFVIIa. There were no thromboembolic complications. APCC and rFVIIa provide an effective and safe first line haemostatic therapy for inhibitor‐positive haemophiliacs, allowing both major and minor surgery to be successfully performed. 相似文献

Spinal epidural haematoma (SEH) is a rare complication in haemophiliacs. We report the case of a 17-year-old boy with severe haemophilia B who presented with acute onset of neck/back pain, walking impairment and urinary retention because of an extensive SEH. The haematoma was identified by magnetic resonance imaging of the spinal column. Prompt and aggressive treatment with factor IX concentrate led to complete recovery at 3 weeks. This case calls attention to the clinical manifestation, radiological features and management options of the rarely reported SEH in haemophiliacs. Despite evidence of extensive SEH, factor replacement therapy and a multidisciplinary team approach result in complete neurological recovery without the need for surgical decompression. 相似文献

Background: Coronary artery anomalies have been reported to show various symptoms ranging from chest pain and dyspnea to cardio-respiratory arrest and sudden death. In this study, we attempted to assess the changes in QT interval duration and dispersion in anomalous origins of coronary arteries (AOCA).
Methods: Nineteen AOCA patients (mean age: 52 ± 11 years) and 30 healthy control subjects (mean age: 50 ± 12 years) were included in the study. Minimum and maximum corrected QT intervals, and corrected QT dispersion were calculated. The two groups were compared in terms of QT dispersion and QT duration.
Results: There was no difference between the two groups in terms of baseline demographic characteristics. Maximum corrected QT intervals (QTc max), minimum corrected QT intervals (QTc min), and corrected QT dispersion were higher in AOCA patients than controls (452 ± 38 vs 411 ± 25 ms [P = 0.0001], 402 ± 31 vs 383 ± 28 ms [P = 0.048], and 51 ± 30 vs 28 ± 12 ms [P = 0.001], respectively).
Conclusion: In the patients with anomalous origins of coronary arteries, QT dispersion that is an indicator of sudden cardiac death and arrhythmias frequency increased. QTc max, QTc min, and corrected QT dispersion are higher in patients with anomalous origin of the coronary artery than in control subjects. 相似文献

Background: Heart rate recovery (HRR) and chronotropic incompetence (CI) in patients with subclinical hypothyroidism (SCH) has not been explored previously. The aim of the present study was to evaluate the HRR and CI in patients with SCH.
Methods: Twenty-five patients (11 men, 14 women with a mean age of 36 ± 10 years) who were diagnosed SCH determined by an increased serum thyrothrophine (TSH) concentration (>4.0 ng/mL) and the normal free triiodothyronine (fT3) and free thyroxin (fT4) levels, were included in the study. The control group of healthy individuals with normal TSH (12 males, 15 females) with a mean age of 36 ± 3 years was also included. Two groups were well matched for age, sex, and body mass index. Medical history, physical examination, electrocardiogram, treadmill exercise testing, and chest radiogram were performed for all participants.
Results: The characteristics of SCH patients and control cases were similar with regard to age, sex, and BMI except for TSH levels. Serum TSH levels were significantly higher in SCH patients than the controls (P < 0.001). No significant differences were observed in the changes of heart rate (HR), exercise tolerance (metabolic equivalents) , or systolic and diastolic blood pressures at rest or during exercise between the groups, whereas HRR and CI were significantly lower during exercise testing in the SCH patients compared to controls (P < 0.003; P < 0.03, respectively).
Conclusion: The results of the present study demonstrated that SCH can cause impaired cardiovascular autonomic function and attenuated HR response to exercise. (PACE 2010; 2–5) 相似文献

Background: The aim of this study was to evaluate the prognostic value of different fractional flow reserve (FFR) cutoff values and corrected thrombolysis in myocardial infarction frame (TIMI) count (CTFC) measurements in a series of consecutive patients with moderate coronary lesions, including patients with unstable angina, myocardial infarction, and/or positive noninvasive functional test findings. Methods: We included 162 consecutive coronary patients in whom revascularization of a moderate coronary lesion was deferred based on a FFR value ≥0.75. Patients were divided according to the results of the intracoronary pressure and flow measurements into four groups: group A: 0.75 ≤ FFR ≤ 0.85 and CTFC > 28 (n=22), group B: 0.75 ≤ FFR ≤ 0.85 and CTFC ≤ 28 (n = 55), group C: 0.85 < FFR and CTFC > 28 (n = 19), and group D: 0.85 < FFR and CTFC ≤ 28 (n = 66). Adverse cardiac events and the presence of angina were evaluated at follow‐up. Results: At a mean follow‐up of 18 ± 10 months, cardiac event rate in patients with 0.75 ≤ FFR ≤ 0.85 and FFR > 0.85 were 22% and 9%, respectively (P = 0.026) and also, a trend was observed toward a higher cardiac event rate in case of an abnormal CTFC (CTFC > 28) compared to a normal CTFC (24% vs 12%, P = 0.066). Furthermore, a significantly higher cardiac event rate was observed when group A was compared to group D (31.8% vs 7.6%, respectively, P = 0.004). Conclusion: Patients with potential microvascular dysfunction and borderline FFR values should be interpreted with caution, and management strategies should be guided not only by pressure measurement, but also by possibly supplementary clinical risk stratification and noninvasive tests.

Summary. Radioisotope synovectomy (RS) is defined as the intra‐articular injection of radioisotopic agents with the aim of fibrosis on hypertrophic synovium in the target joint. The aim of this study was to investigate genotoxic effects on lymphocytes and malign transformation induced by Yttrium90 (Y90) and Rhenium186 (Re186) in children with haemophilia undergone RS. Forty haemophilia patients were enrolled. The mean age was 16.4 ± 6.2 years (range: 8–40). Y90 was used for knees, Re186 was used for other joints. For safety, cytogenetic analysis was performed to determine potential chromosomal changes after RS procedure at three different time points as prior to procedure, 3rd day and 90th day. For the stimulation of chromosomal breakages, diepoxybutane was used (DEB test). Chromosomal breakages (CBs) were found in 23 patients (67.6%) prior to RS. We have found CBs additionally in nine of 11 patients who had no CBs prior to RS after 3 days of radioisotope exposure. At that time, the patients who had CBs were 29 (85.2%). At day 90, only 21 patients revealed (61.7%) CBs. The mean frequency of CBs slightly but not significantly increased in the 3rd day. However, there was a significant decreasing trend between 3rd and 90th days. Radioisotope synovectomy with Y90 and Re186 does not seem to induce the genotoxic effects significantly on peripheral blood lymphocytes. However, CBs even after one year in the re‐evaluation of four patients, significant decrease in the number of CBs between the 3rd and 90th days and de novo CBs after exposure may be accepted as warning signals for young population. It should also be pointed out that families and patients be informed properly related with historical and potential dangers of radioisotopic agents. 相似文献
