1.  Comparison of efficacy and safety of ropivacaine with bupivacaine for intrathecal anesthesia for lower abdominal and lower limb surgeries 
A prospective randomized clinical study was conducted to study the efficacy and safety of ropivacaine with bupivacaine intrathecally for lower abdominal and lower limb surgeries.
Material and Methods:
70 patients aged between 18 to 65 years were randomized into two groups, n = 35 in each group. Group A received 3 ml of (0.5%) isobaric bupivacaine (15 mg) and Group B 3 ml of (0.75%) isobaric ropivacaine (22.5 mg). Spinal anesthesia procedure was standardized. Haemodynamic parameters, onset and duration of sensory and motor blockade, level achieved, regression and side effects were compared between the two groups.
Onset and regression of sensory blockade in ropivacaine group was faster with a P < 0.001 which was statistically significant. Onset of motor blockade was rapid in both the groups but duration of motor blockade was significantly shorter in ropivacaine group. Excellent analgesia, with no side effects and stable haemodynamics was noted in ropivacaine group.
Hence ropivacaine was safe and equally effective as bupivacaine for lower abdominal and lower limb surgeries with early motor recovery, providing early ambulation.

3.  Comparison of the use of McCoy and TruView EVO2 laryngoscopes in patients with cervical spine immobilization 
Saudi Journal of Anaesthesia  2012;6(3):248-253.
The cervical spine has to be stabilized in patients with suspected cervical spine injury during laryngoscopy and intubation by manual in-line axial stabilization. This has the propensity to increase the difficulty of intubation. An attempt has been made to compare TruView EVO2 and McCoy with cervical spine immobilization, which will aid the clinician in choosing an appropriate device for securing the airway with an endotracheal tube (ETT) in the clinical scenario of trauma.
To compare the effectiveness of TruView EVO2 and McCoy laryngoscopes when performing tracheal intubation in patients with neck immobilization using manual in-line axial cervical spine stabilization.
Settings and design:
K. M. C. Hospital, Mangalore, This was a randomized control clinical trial.
Sixty adult patients of either sex of ASA physical status 1 and 2 who were scheduled to undergo general anesthesia with endotracheal intubation were studied. Comparison of intubation difficulty score (IDS), hemodynamic response, Cormack and Lehane grade, duration of the tracheal intubation and rate of successful placement of the ETT in the trachea between TruView EVO2 and McCoy laryngoscopes was performed.
The results demonstrated that TruView has a statistically significant less IDS of 0.33 compared with an IDS of 1.2 for McCoy. TruView also had a better Cormack and Lehane glottic view (CL 1 of 77% versus 40%) and less hemodynamic response.
The TruView blade is a useful option for tracheal intubation in patients with suspected cervical spine injury.

4.  A comparison of hypotension and bradycardia following spinal anesthesia in patients on calcium channel blockers and β-blockers 
Indian Journal of Pharmacology  2012;44(2):193-196.
Hypotension is a common complication of spinal anesthesia and is frequent in patients with hypertension. Antihypertensive agents decrease this effect by controlling blood pressure. There are conflicting reports on the continuation of antihypertensive drugs on the day of surgery in patients undergoing spinal anesthesia. Sudden hypotension could have detrimental effect on the organ systems. This study was undertaken to compare the variation in blood pressure in hypertensive patients on β-blockers and calcium channel blockers undergoing spinal anesthesia.
Materials and Methods:
Ninety patients were enrolled for the study, 30 each in the control, β-blocker and the calcium channel blocker groups.
The incidence of hypotension was not different among the three groups. However, the number of times mephentermine used to treat hypotension was significant in the patients receiving calcium channel blockers while incidence of bradycardia in patients treated with β-blockers was significant (P<0.001).
The incidence of hypotension following spinal anesthesia is not different in patients receiving β-blockers and calcium channel blockers among the three groups.

5.  Comparative evaluation of midazolam and butorphanol as oral premedication in pediatric patients 
To compare oral midazolam (0.5 mg/kg) with oral butorphanol (0.2 mg/kg) as a premedication in 60 pediatric patients with regards to sedation, anxiolysis, rescue analgesic requirement, and recovery profile.
Materials and Methods:
In a double blinded study design, 60 pediatric patients belonging to ASA class I and II between the age group of 2–12 years scheduled for elective surgery were randomized to receive either oral midazolam (group I) or oral butorphanol (group II) 30 min before induction of anesthesia. The children were evaluated for levels of sedation and anxiety at the time of separation from the parents, venepuncture, and at the time of facemask application for induction of anesthesia. Rescue analgesic requirement, postoperative recovery, and complications were also recorded.
Butorphanol had better sedation potential than oral midazolam with comparable anxiolysis at the time of separation of children from their parents. Midazolam proved to be a better anxiolytic during venepuncture and facemask application. Butorphanol reduced need for supplemental analgesics perioperatively without an increase in side effects such as nausea, vomiting, or unpleasant postoperative recovery.
Oral butorphanol is a better premedication than midazolam in children in view of its excellent sedative and analgesic properties. It does not increase side effects significantly.

6.  A comparison of midazolam and clonidine as an oral premedication in pediatric patients 
To compare oral midazolam (0.5 mg/kg) versus oral clonidine (4 μg/kg) as a premedication in pediatric patients aged between 2-12 years with regard to sedation and anxiolysis.
Sixty pediatric patients belonging to the American Society of Anesthesiologists class I and II between the age group of 2-12 years scheduled for elective surgery were randomly allocated to receive either oral midazolam (group I) 30 min before induction or oral clonidine (group II) 90 min before induction of anesthesia. The children were evaluated for levels of sedation and anxiety at the time of separation from the parents, venepuncture, and at the time of mask application for induction of anesthesia.
After premedication, the percentage of children who were sedated and calm increased in both the groups. The overall level of sedation was better in the children in the clonidine group, but children in the midazolam group had a greater degree of anxiolysis at times of venepuncture and mask application. In addition, midazolam did not cause significant changes in hemodynamics unlike clonidine where a significant fall in blood pressure was noted, after premedication, but preinduction.
We conclude that under the conditions of the study, oral midazolam is superior to clonidine as an anxiolytic in pediatric population. Clonidine with its sedative action especially at the time of separation from parents along with its other perioperative benefits cannot be discounted.

7.  Submental intubation in patients with panfacial fractures: A prospective study 
Indian Journal of Anaesthesia  2011;55(3):299-304.
Submental intubation is an interesting alternative to tracheostomy, especially when short-term postoperative control of airway is desirable with the presence of undisturbed access to oral as well as nasal airways and a good dental occlusion. Submental intubation with midline incision has been used in 10 cases from October 2008 to March 2010 in the Department of Oral and Maxillofacial Surgery, Manipal College of Dental Sciences, Mangalore. All patients had fractures of the jaws disturbing the dental occlusion associated with fracture of the base of the skull, or/and a displaced nasal bone fracture. After standard orotracheal intubation, a passage was created by blunt dissection with a haemostat clamp through the floor of the mouth in the submental area. The proximal end of the orotracheal tube was pulled through the submental incision. Surgery was completed without interference from the endotracheal tube. At the end of surgery, the tube was pulled back to the usual oral route. There were no perioperative complications related to the submental intubation procedure. Average duration of the procedure was less than 6 minutes. Submental intubation is a simple technique associated with low rates of morbidity. It is an attractive alternative to tracheotomy in the surgical management of selected cases of panfacial trauma.
