Brief Summary:

Purpose: The aim of this retrospective study is to investigate the end tidal carbon dioxide pressure (ETCO2) values in order to determine the carbon dioxide accumulation under drape and to investigate it's hemodynamic effects based on anesthetic and surgical records in eye surgeries under local anesthesia.

Methods: The data were collected from anesthetic records of the patients who were followed with noninvasive capnograph (Capnostream 20 p, Oridion®, Israel) by the anesthesiology department in the operating room at Duzce University Faculty of Medicine Hospital during the period of January 2016 to December 2016.

Collected data from the 42 patients' records were systolic, diastolic and mean arterial pressures, operation duration, total local anesthetic and, heart rate, ST segment analysis, ETCO2 pressure, pulse oximeter values.

The time periods of collected datas were determined as: after the anesthesia and before drape closure (baseline level), at 10th, 15th, 20th, 45th of the surgery and 5 minutes after drape removal.

Detailed Description:

After approval from the Duzce Faculty of Medicine Noninvasive Researches Ethics Committee (02.01.2017), the datas were collected patients anesthetic forms who were followed with capnograph (Capnostream 20 p, Oridion, Israel) by the anesthesiology department for eye surgery in the operating room at Duzce University Faculty of Medicine Hospital during the period of 01 January 2016 to 31 December 2016. It was observed that 42 patient records met the study criteria. Demographic and clinical datas were abstracted from anesthetic and clinical records.

Age, weight, height of the patients, operation types, operation duration times, local anesthetic performing types, noninvasive systolic, diastolic and mean arterial pressures, cardiac rates, ST segment analysis (Datex Ohmeda monitor, GE Health Care, Finland) ( This monitor use for the routine monitorisation in the eye surgery operating room in our hospital) systolic, diastolic and mean arterial pressure measurements, end tidal carbon dioxide levels, pulse oximeter values were extracted from anesthetic forms retrospectively.

Arrhythmia recordings were evaluated as (yes / no) over time periods. Surgical field was covered with reusable cotton fabric drape or dispossible surgical adhesive plastic drape (SteriDrape, 3M). We included the patients records who were covered with the same kind of drapes (SteriDrape, 3M). We excluded records with another type of drapes usage or without any data about drape type to provide the homogenisation and clearity of the results.

Datas were collected from the anesthetic forms which time periods were determined as the baseline, before closing drape, at 10th, 15th, 20th, 45th minutes after covering and 5 minutes after drape removal. Records with pulmonary disease, diabetes mellitus and sedative usage, alcohol usage were excluded from the study.

The comparisons were made with patients basal status and time periods statistically.
