Randomized Controlled Trial Comparative Study
Nitrous oxide pollution in the operating room. A comparison of two modes of ventilation.
The use of laryngeal mask airway (LMA) as an alternative to the endotracheal tube (ETT) is becoming more popular in the practice of anesthesia. It is undeniable that this device has numerous advantages over endotracheal tube, however it does not provide an airtight seal between the airway and atmospheric gases. ⋯ The airway in Group I was maintained with LMA with spontaneous ventilation and ETT with intermittent positive pressure ventilation (IPPV) was used for Group II. The result demonstrated that the ETT group recorded concentrations of nitrous oxide that were well above the NIOSH recommended eight hour time weighted average of 25ppm throughout the duration of surgery when compared to patients using LMA.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparative study of intravenous patient-controlled analgesia morphine and tramadol in patients undergoing major operation.
The success of major surgery depends partly on providing effective post-operative pain relief, which can be commonly achieved by morphine administration via patient- controlled analgesic (PCA) system. Alternatively, tramadol which is a weak opioid analgesic, can be used for post operative pain relief. The purpose of this study was to evaluate the effectiveness of intravenous PCA tramadol in comparison with PCA morphine in term of analgesic properties, sedation and side effects. ⋯ The incidence of nausea, vomiting and pruritus were the same in the two groups. This study indicates that PCA tramadol is as equally effective as PCA morphine control following major surgery. The incidences of sedation, nausea or pruritus were the same in the two groups.

Randomized Controlled Trial
Comparison of the ease of insertion of the laryngeal tube VBM and laryngeal mask airway during manual in-line neck stabilization.
The purpose of this study is to assess whether the newly developed laryngeal tube (LT) VBM is easy, simple to use and able to provide adequate ventilation and oxygenation to a patient with an unstable neck who required airway management. We compared the LT to the laryngeal mask airway (LMA) as alternative airway management tool in adult patient with unstable neck who underwent intubation with manual in-line neck stabilization. A randomized single-blinded prospective study was conducted involving a total of 40 ASA I and II premedicated patients who were divided into two groups with 20 patients for each group; either LT or LMA group for airway management during elective surgery. ⋯ There was a statistically significant difference for both groups in the time required for successful insertion (time required for LT was 24.8 +/- 7.7 seconds and LMA was 36.1+/-17.3 seconds) (p= 0.01). There was no statistical differences (p>0.05) in number of attempts needed to achieve a patent airway although we were able to achieve a clear airway in all patients in LT group at the first attempt compared with 85% in LMA group. successful insertion rate was 100% for both groups. We conclude that the LT is easier to insert and is a suitable alternative to the LMA for airway management when the patient's head and neck are stabilized by manual in-line method.

Randomized Controlled Trial Comparative Study
A prospective comparison of percutaneous endoscopic gastrostomy and nasogastric tube feeding in patients with acute dysphagic stroke.
Dysphagia following stroke is common problem and is of particular concern because of its potental for malnutrition. Nasogastric (NG) and percutaneous endoscopic gastrostomy (PEG) tube feeding are recognized methods for nutritional support for patients with persistent neurologic dysphagia. However, the former is associated with tube dislodgement and blockage that might compromise the patients' nutritional status. ⋯ Treatment failure occurred in 5 out of 10 patients (50.0%) in the NG group, but none in PEG group (p = 0.036). PEG tube feeding is more effective than NG tube feeding in improving the nutritional status (in terms of the serum albumin level) of patients with dysphagic stroke. NG tube feeding, in fact, reduced the nutritional status (in terms of the serum albumin level) of the patients.

Randomized Controlled Trial Comparative Study
Comparison of intra-articular analgesics for analgesia after arthroscopic knee surgery.
Post Arthroscopic intra-articular analgesia is a better method to avoid post-operative pain after arthroscopic surgery, thus avoiding the adverse effects of systemic analgesics. In this prospective randomized double blind study conducted on 90 patients, 30 patients in group A received 20 ml of intra-articular saline, 30 patients in Group B received 10 ml of intra-articular saline and 10 ml of 0.25% bupivacaine and 30 patients in Group C received 10 ml of 0.25% bupivacaine, 1 ml (30 mg) of ketorolac and 9 ml of saline intra-articularly. ⋯ This combination significantly prolonged the duration of analgesia. Patients receiving this combination of drugs for intra-articular analgesia ambulated earlier.
