Role of newer imaging modalities for airway assessment in dynamic tracheal compression.

Anesthetic management of a patient with tracheal stenosis is challenging. Though we have newer imaging modalities like multislice, three-dimensional computerized tomography, virtual bronchoscopy to determine the size and anatomy of the airway, it is difficult to accurately predict the distensibility of the trachea with the available preoperative tests. With our experience in this case, we believe that newer imaging modalities are just an adjunct in the assessment of the compromised airway in case of dynamic compression. Clinical assessment is very important in deciding the plan of management.

Efficacy and safety of a mixture of ketamine, midazolam and atropine for procedural sedation in paediatric oncology: a randomised study of oral versus intramuscular route.

AIM: To evaluate the efficacy and safety of a mixture of ketamine, midazolam and atropine given orally by comparing the same mixture given through the intramuscular route in children with malignancy undergoing minor invasive procedures. METHODS: Sixty children, aged between 1 and 10 years, scheduled to undergo minor procedures were randomised into two groups to receive a mixture of ketamine (6 mg/kg), midazolam (0.05 mg/kg) and atropine (0.02 mg/kg) intramuscularly (Group 1) or ketamine (10 mg/kg), midazolam (0.2 mg/kg) and atropine (0.05 mg/kg) orally (Group 2). Sedation score, observer-rated visual analogue scale for pain were noted by an observer blinded to the route of drug administration. RESULTS: Optimum sedation was present in all children in both groups after drug administration, with Group 1 being more deeply sedated than Group 2 at the start of the procedure. Supplementation with intravenous ketamine was required in four children in Group 1 and eight children in Group 2 (P = 0.33). The mean (+/-SD) observer-rated visual analogue scale for pain during the procedure was 8.33 (+/-15.99) and 9.33 (+/-16.39) in Group 1 and Group 2, respectively (P = 0.892). One patient in Group 1 had vomiting after the procedure. There were no differences in proportion of patients with hallucinations and nystagmus in both groups. CONCLUSIONS: A mixture of ketamine, midazolam and atropine given orally provides sedation and analgesia similar to that produced by the same drugs given intramuscularly. It offers advantage over the intramuscular route as it is painless and can be given for minor paediatric oncology procedures with appropriate monitoring.

Cancer pain management at a tertiary care cancer center in India--a retrospective analysis of 3,238 patients.

Effective pain control is essential for the management of patients with cancer. About 70-80 percent of patients with cancer present in an advanced stage of disease. Patients with advanced cancer frequently experience intractable pain, with diverse symptoms that can make daily living impossible and affect the quality of life. This article reports the management of 3,238 patients with cancer pain over a period of five years. Nearly 89.6 percent patients had good pain relief with Visual Analogue Scale score less than 3. These promising results were achieved by careful patient assessment, close liaison with clinicians from other specialties, and using a variety of analgesic regimen including oral analgesics, anesthetic procedures, psychological interventions, and supportive care. However, the main stay of treatment was oral analgesics, following the principles of World Health Organization ladder, with continuing follow-up.

Preemptive antiemesis in patients undergoing modified radical mastectomy: oral granisetron versus oral ondansetron in a double-blind, randomized, controlled study.

STUDY OBJECTIVE: To assess the efficacy of oral granisetron versus oral ondansetron for preemptive antiemesis in women undergoing modified radical mastectomy. DESIGN: Randomized, double-blind, controlled study. SETTING: Metropolitan hospital. PATIENTS: Ninety ASA physical status I and II hospitalized female patients, aged 18 to 65 y, scheduled for modified radical mastectomies. INTERVENTIONS: Patients were assigned to receive orally placebo, granisetron 2 mg, or ondansetron 4 mg (n = 30 in each group) 1 h before induction of anesthesia. A standard general anesthetic technique and postoperative analgesia were used. MEASUREMENTS: Postoperative nausea and vomiting and safety assessments were performed continuously 0 to 2, 2 to 6, 6 to 12, and 12 to 24 h after anesthesia. MAIN RESULTS: A complete response during 0 to 2 h after anesthesia was found in 43%, 63%, and 90% of patients who had received placebo, granisetron, or ondansetron, respectively; corresponding percentages of patients requiring rescue antiemetics were 40%, 17%, and 7%. Frequency of nausea and vomiting was low (less than 23%) after 2 h in the three groups. Observations of postoperative nausea and vomiting score and need for antiemetics at other time intervals (2 to 6, 6 to 12, and 12 to 24 h) were not significantly different among the three groups. CONCLUSION: Oral ondansetron 4 mg provided better preemptive antiemesis than oral granisetron 2 mg in the 2 h after modified radical mastectomy during general anesthesia.
