Brief Summary

Laryngeal Mask is widely used for air-way management during anaesthesia. Pharyngolaryngeal morbidity linked to laryngeal mask use is related to correct choice of mask size, placement technique, placement of the laryngeal mask in the correct position on the larynx, cuff volume and cuff pressure. It has been stated that keeping laryngeal mask cuff pressure below 45 mmHg (60 centimeter of water(cmH2O) ) can prevent pharyngolaryngeal morbidity related to laryngeal mask (throat pain, dysphonia, dysphagia) and shown that using a manometer after Laryngeal Mask Unique placement to limit pressure within the cuff can reduce this morbidity by nearly 70%. Studies commenting on pharyngolaryngeal morbidity generally do not choose a certain age group and cover stages including very young and middle-aged groups. In the literature only one similar study on the geriatric age group was found. The aim of this study is to compare the postoperative pharyngolaryngeal morbidity in a group with cuff pressure held to 44 mmHg (60 cmH2O with a manometer and a group with Laryngeal Mask cuff inflated without reference to pressure in the geriatric age group with indications for Laryngeal Mask Unique placement.

Outcome Measures

Primary Outcomes (1)

  • Postoperative Pharyngolaryngeal Morbidity Postoperative 1.Hour

    The primary outcome was a composite endpoint of any pharyngolaryngeal complications such as sore throat, dysphonia and dysphagia according to Likert scale ranges from 1 (none) to 4 (severe) at postoperative 1.hour

    Postoperative 1.hour

Secondary Outcomes (1)

  • Postoperative Pharyngolaryngeal Morbidity at Postoperative 24.Hour

    Postoperative 24.hour

Study Arms (2)

Group Routine Care

ACTIVE COMPARATOR

The placement according to the manufacturer's instructions.

Procedure: The placement according to the manufacturer's instructions

Group Pressure Limiting

EXPERIMENTAL

Cuff inner pressure was held below 44 mmHg

Procedure: Cuff inner pressure was held below 44 mmHg

Interventions

Before insertion the laryngeal mask used in daily routine (Laryngeal Mask Unique®(LMU)) was lubricated with a water-based gel and the cuff was completely deflated. After induction when BIS values were between 40 and 60 and sufficient chin relaxation was obtained for patients weighing less than 50 kg no. 3 LMU, for those between 50-90 kg no. 4 and for patients above 90 kg no. 5 LMU was inserted by an anesthetist with more than five years experience

Group Routine Care

cuff pressure limitation (Group Pressure Limiting (PL), n=45) cuff inner pressure was held below 60 cmH2O (44 mmHg)
