Regional anesthesia is a popular anesthetic method in patients who will undergo an inguinal
hernia operation. Researchers known that pain in the operating area is a complaint that
impairs the quality of life for patients in the long term after the operation. In addition to
regional anesthesia, has planned to investigate the effects of applying another drug near the
surgery area on pain that may develop in the long term.
Prospective clinical assessment of 40 Hyperbaric Oxygen (HBO) treatments in 10 completed
In the investigator’s institute there is ongoing treatment of different patients with
cognitive deficits using Hyperbaric oxygen therapy (HBOT). These patients undergo
neuro-cognitive function computerized tests before and after treatment.
The aim of this study was to retrospectively evaluate the cognitive changes before and after
HBOT in different patients populations.
The objective of this study is to compare the incidence of postoperative urinary retention
related to spinal anesthesia with morphine and spinal anesthesia associated with peripheral
blockade in orthopedic procedures of lower limbs. Secondary objectives are assessing the
incidence of nausea and vomiting; postoperative pain and opioid consumption at 24 hours after
surgery with each of the techniques. A total of 52 patients submitted to a lower limb
orthopedic procedure were randomized to the intervention groups: spinal anesthesia with
morphine versus spinal anesthesia without opioid associated with peripheral nerve block.
After surgery, bladder ultrasound will be performed in post-anesthesia care unit to identify
urinary retention and patients will be followed for 24 hours to assess outcomes.
Spinal anaesthesia has the advantage that produced nerve block by the injection of local
anaesthetic into cerebrospinal fluid (CSF). However, the greatest challenge in spinal
anaesthesia is to control the spread of local anaesthetic through the CSF to provide a block
which is adequate for the proposed surgery without unnecessary extensive spread, and
increased risk of complications.
The aim of the current study was to examine the effect of short-term HBOT (hyperbaric oxygen
treatments) on a range of cognitive abilities. The current study examined whether there is a
HBOT-related short-term cognitive improvement and, if so, what specific cognitive abilities
are improved by the intervention.
Participants were randomized to perform cognitive tasks in one of two chambers with two
different clinical environments: (a) HBOT condition: (2 ATA (atmosphere absolute) 100% oxygen
for 90 minutes). (b) Control condition: in which the chamber was not pressurized (Normobaric
condition- 1 ATA for 90 minutes).
