BACKGROUND The purpose of present study was to compare and evaluate both topical lignocaine and intravenous lignocaine for laryngeal mask airway (LMA) insertion prior to propofol. Main objective was to study the conditions for LMA insertion with respect to gagging, coughing, Laryngospasm and No. of attempts for LMA insertion and also study the hemodynamic parameters in both the groups (Heart rate, SBP,DBP, MAP, SpO2) METHODS This study included 60 patients of 30 in each group, ASA I & II day care surgeries were performed in our hospital between 2019 and 2021. Patients were randomized into two groups. Group I received intravenous lignocaine 1.5 mg / kg over 30 seconds and group II received topical lignocaine 40 mg. Conditions of LMA insertion, gagging, laryngospasm, coughing were noted at the time of insertion, ECG, NIBP, SPO2 and ETCO2 were recorded according to scheduled times. RESULTS In conditions of LMA insertion, difference between both the groups was found to be significant, P < 0.05 in groups with first minute rise in heart rate, fall in Systolic blood pressure, diastolic blood pressure, mean arterial pressure was significant. At two minutes and three minutes after the LMA insertion, HR, SBP, DBP, MAP all these parameters changed slightly but these changes were statistically not significant. CONCLUSIONS Prior to Propofol induction, compared to intravenous lignocaine, topical lignocaine 10 % aerosol provided excellent conditions for the insertion of LMA without the use of neuromuscular blockers.

Purpose: Volume-controlled ventilation (VCV) has been the traditional mechanical ventilation mode in laparoscopic surgery. Pressure-controlled ventilation (PCV) has been used more frequently in recent years, especially for patients with complicated conditions; however, evidence on whether PCV is superior to VCV is still lacking. A meta-analysis was used to compare the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. Methods: PubMed and Embase were each searched from their inception to December 2014 for randomized controlled trials comparing the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. Standard mean difference (SMD) with 95% confidence interval (CI) was calculated using a random effect model. Outcomes were assessed at three times: preoperative (T1), intraoperative (T2) and postoperative (T3). Respiratory mechanics (including peak airway pressure, plateau pressure, mean airway pressure, compliance, airway resistance, minute volume, end-tidal CO2 tension and tidal volume) and hemodynamic parameters (including heart rate and mean arterial pressure) were calculated. Results: Eight randomized controlled trials with a total of 428 participants, 214 cases using PCV and 214 cases using VCV, were included in the meta-analysis. No significant differences were detected between the groups in terms of hemodynamic parameters. In contrast, with respiratory mechanics, PCV was slightly but significantly associated with lower peak airway pressure, higher compliance, lower airway resistance at T1, lower peak airway pressure, higher compliance, higher mean airway pressure at T2, lower peak airway pressure, lower mean airway pressure and higher end-tidal CO2 tension at T3. For the rest of respiratory parameters, there were no statistical differences between the groups. Subgroup analysis by morbidly obese, type of operations and quality of studies, showed similar results. Conclusions: Our meta-analysis suggests that hemodynamic parameters are similar in patients who underwent laparoscopic surgery with PCV and VCV, but patients who had PCV exhibited mildly better respiratory data.

Background: Laparoscopic surgery is preferred for its advantages in shorter hospital stay, less amount of blood loss and aesthetic incisions. The problems are however evident when the complications of hemodynamic disturbances are enhanced due to pneumoperitoneum. Several newer formulations have ben tried to overcome this problem so that issues of hemodynamic stability can be addressed. Aim: The present study aims to comparatively evaluate the hemodynamic effects of dexmedetomidine and fentanyl in subjects undergoing elective laparoscopic surgeries. Methodology: The study involved a subject pool of 60 patients who were divided equally in two groups and administered the study drugs. Parameters of hemodynamic stability were recorded and analysed to ascertain comparative efficacy. Observations: The mean HR, SBP, DBP, MAP and sedation score were better in dexmedetomidine group as compared to fentanyl group. Conclusion: Dexmedetomidine is an effective adjuvant to anaesthetic medications in laparoscopic surgeries with a disadvantage of longer surgery duration as compared to fentanyl.

The Relationship

A custom in-the-ear (ITE) hearing aid fitting was compared to two over-the-ear (OTE) hearing aid fittings for each of 9 subjects with mild to moderately severe hearing losses. Speech intelligibility via the three instruments was compared using the Speech Intelligibility Rating (SIR) test. The relationship between functional gain and coupler gain was compared for the ITE and the higher rated OTE instruments. The difference in input received at the microphone locations of the two types of hearing aids was measured for 10 different subjects and compared to the functional gain data. It was concluded that (a) for persons with mild to moderately severe hearing losses, appropriately adjusted custom ITE fittings typically yield speech intelligibility that is equal to the better OTE fitting identified in a comparative evaluation; and (b) gain prescriptions for ITE hearing aids should be adjusted to account for the high-frequency emphasis associated with in-the-concha microphone placement.
