Abstract

Objective:

To investigate the impact of parecoxib and transversus abdominis plane block on postoperative anxiety and early cognitive function in patients undergoing laparoscopic intestinal surgery.

Methods:

The multicentre, randomised controlled trial was conducted at three tertiary hospitals in China from September 1, 2020, to September 30, 2022, and comprised individuals aged 60-85 years scheduled for elective laparoscopic intestinal surgery They were randomised into 4 groups. Patients in group C received normal saline. Patients in group P were given parecoxib 40mg intravenously 30 minutes before the start of surgery and 10 minutes after the end of surgery. In group T, a bilateral transversus abdominis plane block was performed 30 minutes before the start of surgery. Patients in group PT received a combination of interventions used in groups P and T. Serum samples of all the patients were obtained one day before surgery, 30 minutes after surgery and 24 hours after surgery. Anxiety levels were assessed one day before surgery, 24 hours after surgery, and 7 days after surgery. Data was analysed using SPSS 25.

Results:

Of the 205 patients, 115(56%) were males and 90(44%) were females. There were 51(24.9%) patients in group C with mean age 67.61±5.46 years, 51(24.9%) in group P with mean age 66.53±4.30 years, 52(25.3%) in group T with mean age 67.23±5.36 years and 51(24.9%) in group PT with mean age 66.49±4.62 years. Compared to group C, anxiety scores in groups P and PT were significantly lower at 24 hours post-surgery (p<0.05). Compared to group C, the concentration of tumour necrosis factor-alpha in the serum samples of groups P and group PT was significantly lower at 30 minutes after surgery (p< 0.05).

Conclusions:

A single transversus abdominis plane block did not have a significant effect on postoperative anxiety and cognition, while parecoxib could alleviate postoperative anxiety in elderly patients undergoing laparoscopic intestinal surgery.

General Anesthesia: Overview

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Anxiolytic Drugs: Overview

Anxiolytic Drugs: Overview

Anxiolytic drugs are vital in managing anxiety disorders by effectively alleviating symptoms such as excessive fear, tachycardia, and tremors. There are several classes of anxiolytic medications, each with unique mechanisms of action and potential side effects.
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic...

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Anxiolytic Drugs: Benzodiazepines and Buspirone

Anxiolytic Drugs: Benzodiazepines and Buspirone

Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Inflammatory Bowel Disease V: Surgical Management

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
