Immediate Post-operative Recovery After Regional vs. General Anesthesia

May 7, 2018 updated by: University of Zurich

Immediate Post-operative Outcome After Regional vs. General Anesthesia

Early post-anesthesia status of patients emerging from surgery encompasses vital respiratory and hemodynamic parameters as well as subjective signs of well-being such as absence of nausea, vomiting and a low pain level. This investigation intends to compare the rate of postoperative complications in the 2 groups from pair matched patient records after regional anesthesia with otherwise similar patients after general anesthesia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

It is still unclear whether the immediate post-operative condition of patients after surgery and anesthesia is dependent on the basic anesthesia technique (General vs. regional anesthesia). The patients' post-anesthesia presentation encompasses vital respiratory and hemodynamic parameters as well as subjective signs of well-being such as absence of nausea, vomiting and a low pain level. By pair matching of patient records after regional anesthesia with otherwise similar patients after general anesthesia (control group), the rate of postoperative complications in the 2 groups will be compared. The results of this investigation will help to answer what is the difference in complication rates and wellbeing of patients depending on their previous anesthesia. The results of this study will Show which basic anesthesia technique has more or less early complications.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Hospital records from patients after surgery in regional anesthesia that have postoperative quality control data plus a same sized matched pairs control group after general anesthesia.

Description

Inclusion Criteria:

  • Records from regional anesthesia cases on adults which have quality control assessment data, plus the same number of matched pairs who had general anesthesia.

Exclusion Criteria:

  • Cases with incomplete quality control assessment data.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Regional Anesthesia
Hospital records from patients who have undergone surgery in regional anesthesia.
Other: Data mining from records
The relevant data for this investigation is extracted from the patient records database as well as from the assessment results of the ongoing quality control process that were collected by the nursing staff of the postoperative recovery units.
General Anesthesia
Hospital records from patients who have undergone surgery in General anesthesia.
Other: Data mining from records
The relevant data for this investigation is extracted from the patient records database as well as from the assessment results of the ongoing quality control process that were collected by the nursing staff of the postoperative recovery units.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Postoperative complications during inhospital stay up to 30 days
Time Frame: 1 March to 30 November 2017
Number participants who had one or more cardiovascular events up to discharge or 30 days
1 March to 30 November 2017
Postoperative complications during inhospital stay up to 30 days (PONV) - Duration of pain (VAS > 3) episodes in hours; days up to discharge or max. 30 days
Time Frame: 1 March to 30 November 2017
Number of PONV episodes up to discharge or max. 30 days Duration of PONV episodes in days; hours up to discharge or max. 30 days
1 March to 30 November 2017
Postoperative complications during inhospital stay up to 30 days (pain)

Duration of pain (VAS > 3) episodes in hours; days up to discharge or max. 30 days
1 March to 30 November 2017

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
