About this study

Official title: The Use of LMA-Proseal and Endobronchial Blocker for One Lung Anesthesia, Case Series.

An observational pilot study to determine the success rate of using LMA Proseal in conjuction with endobronchial blocker to provide one-lung anesthesia for thoracic surgery.

Read the detailed description

The use of LMA has gained popularity secondary to benefits confirmed by many literatures. However, LMA is rarely used in thoracic surgery. To enable one-lung ventilation, the LMA need to be used with bronchial blocker. The use of this combination has been reported as a rescue technique in special clinical scenarios, i.e. patient with difficult airway. When used in patient with difficult airway, the LMA will be inserted until proper ventilation achieved, then endobronchial blocker will be subsequently placed through the LMA into the selected main bronchus. The success rate of the the bronchial blocker placement via properly placed LMA has never been studied. This pilot study was designed to evaluate the success rate, the quality of lung collapsed, the dislodgement or other associated problems including some minor complications i.e. postoperative dysphagia, sore throat hoarseness of voice.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. success rate

    can provide one-lung ventilation within 15 mintues

    Measured: 15 mintues

Secondary outcomes (4)
  1. Time consuming in achieving one-lung anesthesia

    Total time spent to place bronchial blocker into the selected main bronchus shall not exceed 15 minutes. If investigators failed, the study will be terminated and patient will receive appropriate conventional airway management.

    Measured: 15 mintues

  2. Sorethroat

    Patient self assessment scale as followed 0 - no sore throat

    1. - mild sore throat (no pain at rest, only with swallowing, does not require intervention)
    2. - moderate sore throat (some discomfort at rest, more with swallowing - but does not need medications)
    3. - severe sore throat (at rest, require analgesics for sore throat)

    Measured: 1 day

  3. Hoarseness of voice

    Patient assessment scale by visitor as followed 0 - no hoarseness of voice detected, normal voice.

    1. - some hoarseness of voice detected but able to speak in all octaves.
    2. - notable hoarseness of voice, unable to phonate in high pitch.
    3. - marked hoarseness of voice, unable to phonate

    Measured: 1 day

  4. Difficulty swallowing

    Patient self assessment and visitor assessment in scale as followed. 0 - no problem swallowing. no pain.

    1. - some sore throat (grade 1) with swallowing but able to swallowing both liquid and solid.
    2. - moderate swallowing limitation, only liquid or soft diet swallowing - unable to swallow solid food
    3. - marked swallowing limitation, patient prefers to fast due to pain associated with swallowing. Speech therapist/OT/PT consult to evaluation swallowing problems

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Anesthetic Technique and One-lung Ventilation, run by Mahidol University at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

success rate (time frame: 15 mintues). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2014.
