About this study
Official title: Effects of Operating Table Height on Subarachnoid Block Success by Anesthesia Residents in Faculty of Medicine University of Indonesia
Operating table height influences operator comfort and performance during neuraxial anaesthesia, particularly when the patient is positioned sitting. This study aimed to analyse the effect of operating table height on the success rate and incidence of complications during spinal anesthesia, particularly done by trainees/residents.
Read the detailed description
Patients who met the inclusion criteria and did not meet any exclusion criteria were randomised by computer software into two groups according to operating table height - set with puncture site at the level of the operator's umbilicus or the operator's xiphoid process - with group allocation concealed in opaque envelopes. Operators were enrolled by consecutive sampling, consisting of anaesthesiology residents who met the eligibility criteria and were present in the operating theatre during the study period. The outcomes assessed included subarachnoid block success, procedural duration from needle insertion to free flow of cerebrospinal fluid, the need for needle redirection, the need for needle reinsertion, operator comfort, operator posture analysis, and minor complications such as paresthesia or vascular puncture

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Table heightBehavioural
Table height set so that the puncture site is at operators' umbilicus or xyphoid process level
| Study group | Role | What they receive |
|---|---|---|
| Umbilicus | Experimental | Patients with table height set so that the puncture site is at operators' umbilicus level Receives: Behavioral: Table height |
| Xyphoid process | Experimental | Patients with table height set so that puncture site is at the operators' xyphoid process level Receives: Behavioral: Table height |
What is being measured
The primary outcome is the main question the study is designed to answer.
Procedure sucess
Determined as free flowing cerebrospinal fluid in spinal needle hub with total procedure time less than 10 minutes, redirection less than 5 minutes, and reinsertion less than 3 times, without occurrence of paresthesia and bloody tao
Measured: Periprocedural
Secondary outcomes (9)
Time to sucess
Time needed from spinal needle-skin contact to free flow of cerebrospinal fluid
Measured: Periprocedural
Redirection
Numbers of needle redirection needed at the same puncture site
Measured: Periprocedural
Reinsertion
Numbers of spinal needle insertion (after fully pulled out from the skin)
Measured: Periprocedural
Paresthesia
Abnormal unpleasant sensation (tingling, burning electric shock, or pain) on lower limbs during spinal procedure
Measured: Periprocedural
Blood contamination
Blood observed in spinal needle hub that went away after needle redirection
Measured: Periprocedural
Bloody tap
Aspirated blood in spinal needle hub that persists even after needle redirection and necessitate a reinsertion
Measured: Periprocedural
Subjective comfort assessment
Subjective assessment of perceived comfort during procedure, asked simply as "comfortable" or "uncomfortable"
Measured: Periprocedural
Musculoskeletal complaints
Perceived sensation of aches, pains, tiredness, or stiffness in certain body areas as measured by nordic body map. Minimum value is 0 and maximum value is 28. Higher scores mean worse outcome.
Measured: Periprocedural
Body postures score
Assessment of forced posture risk scoring using Rapid Entire Body Assessment. Minimum value is 1 and maximum value is 15. Higher scores mean worse outcome.
Measured: Periprocedural
