[PMID: 32682668 DOI: 10.1016/j.jopan.2020.03.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 03/11/2020] [Accepted: 03/14/2020] [Indexed: 11/16/2022]
Abstract
PURPOSE The aim of this study was to investigate the effect of a small priming dose of sufentanil on sufentanil-induced cough during induction of anesthesia. DESIGN Randomized controlled trial. METHODS Adult patients (N = 220) aged 18 to 65 years undergoing general anesthesia were randomized into two groups (n = 110), a total dose of sufentanil 0.4 mcg/kg was used during induction of anesthesia. Group P (intervention) received a bolus of 5 mcg of sufentanil 1 minute before a bolus of the remaining larger dose of sufentanil, whereas group C (comparison) received an equal volume of normal saline 1 minute before a bolus of the total dose of sufentanil. The incidence and severity of cough were noted for 1 minute after each injection of sufentanil or normal saline. FINDINGS The incidence of cough in group P was significantly lower than group C (6.4% vs 21.8%, P < .001). The severity of cough in group P was significantly decreased compared with group C (P < .001). In group P, three patients (2.7%, P = .247) coughed after the priming sufentanil injection. CONCLUSIONS A priming dose of 5 mcg of sufentanil 1 minute before a larger dose of sufentanil injection could effectively alleviate sufentanil-induced cough, the small priming dose of sufentanil could also elicit cough with a low incidence.

Cough Suppression during Flexible Bronchoscopy Using Transcutaneous Electric Acupoint Stimulation: A Randomized Controlled Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:5650413. [PMID: 31827553 PMCID: PMC6885814 DOI: 10.1155/2019/5650413] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2019] [Revised: 09/18/2019] [Accepted: 10/16/2019] [Indexed: 11/24/2022]
Abstract
Background and Objective. Transcutaneous electric acupoint stimulation (TEAS) is recommended for its sedative and analgesic effects. We sought to evaluate the effect of TEAS on cough suppression during flexible bronchoscopy (FB) and explore the underlying mechanism. Methods. In this single-center, randomized, single-blind, parallel-controlled study, we randomized 100 patients scheduled for FB into two equal groups treated with or without TEAS (TEAS group and control group). Patients in the TEAS group received 30 min of stimulation at the Hegu (LI4), Neiguan (PC6), and Lieque (LU7) points before FB. The control group underwent the same procedure, but without stimulation. The primary outcome was the intraoperative cough score determined by the bronchoscopist. The secondary outcomes were patient-reported discomfort scores and other procedural parameters. Results. Compared with the controls, patients who received TEAS preconditioning had lower cough scores (P=0.0027) and requirement of lidocaine and fentanyl (P < 0.05) and significantly higher postprocedural plasma β-endorphin levels (P=0.0367). There were no intergroup differences in discomfort scores, midazolam dosage, rate of premature termination, oxygen requirement, sedation level, airway assistance, oxygen saturation, lowest oxygen saturation level, heart rate, plasma substance-P levels, and rate of complications after 24 h. The total procedure duration, time for passage of the bronchoscope through the vocal cords, and systolic and diastolic blood pressure levels were less in the TEAS group than in the control group (P=0.033, 0.039 and <0.05, respectively). Conclusion. The combination of midazolam and TEAS was superior to midazolam alone for cough suppression during FB, probably due to increased plasma β-endorphin levels. This trial is registered with ChiCTR1800016612 at chictr.org.cn/index.aspx.

Abstract
Following systemic administration, centrally acting antitussive drugs are generally assumed to act in the brainstem to inhibit cough. However, recent work in humans has raised the possibility of suprapontine sites of action for cough suppressants. For drugs that may act in the brainstem, the specific locations, types of neurones affected, and receptor specificities of the compounds represent important issues regarding their cough-suppressant actions. Two medullary areas that have received the most attention regarding the actions of antitussive drugs are the nucleus of the tractus solitarius (NTS) and the caudal ventrolateral respiratory column. Studies that have implicated these two medullary areas have employed both microinjection and in vitro recording methods to control the location of action of the antitussive drugs. Other brainstem regions contain neurones that participate in the production of cough and could represent potential sites of action of antitussive drugs. These regions include the raphe nuclei, pontine nuclei, and rostral ventrolateral medulla. Specific receptor subtypes have been associated with the suppression of cough at central sites, including 5-HT1A, opioid (mu, kappa, and delta), GABA-B, tachykinin neurokinin-1 (NK-1) and neurokinin-2, non-opioid (NOP-1), cannabinoid, dopaminergic, and sigma receptors. Aside from tachykinin NK-1 receptors in the NTS, relatively little is known regarding the receptor specificity of putative antitussive drugs in particular brainstem regions. Our understanding of the mechanisms of action of antitussive drugs would be significantly advanced by further work in this area.

Abstract
The role of cyclin-dependent kinase 5 (Cdk5) in the capsaicin-induced cough reflex was examined in mice. Pretreatment with inhaled roscovitine, a selective Cdk5 inhibitor, at concentrations of 0.3 to 3 mM inhibited the number of capsaicin-induced coughs in a concentration-dependent manner. Pretreatment with inhaled roscovitine, at a concentration of 3 mM also slightly but significantly inhibited the number of citric acid-induced coughs. The number of capsaicin-induced coughs was significantly reduced when C-fibers were desensitized by the pretreatment with capsaicin. The number of citric acid-induced coughs was slightly but significantly reduced in capsaicin-pretreated mice as compared with that in naive mice. Although the inhalation of roscovitine at a concentration of 3 mM significantly reduced the number of citric acid-induced coughs in naive mice to the level observed in capsaicin-pretreated mice, roscovitine had no effect on the number of citric acid-induced coughs in capsaicin-pretreated mice. These results suggest that Cdk5-dependent factors are involved in C-fiber-mediated cough signaling.

Abstract
Angiotensin Converting Enzyme Inhibitors (ACEI) like captopril and enalapril, can induce persistant cough in man. Noscapine, an antitussive alkaloid, can be used to suppress ACEI-induced cough. Some workers have suggested a role for bradykinin in precipitation of ACE-induced cough. Work carried out in our laboratory has shown noscapine to be a non-competitive inhibitor of bradykinin in guinea pig ileum. It is therefore possible that noscapine suppresses cough by blocking the effect of bradykinin receptor activation in the airways. Guinea pigs were placed in a cough-chamber connected to an air pump and a pressure transducer. Capsaicin was sprayed into the chamber and cough was recorded as a distinctive change in air pressure inside the cough-chamber. Animals treated with 1 mg/kg captopril and enalapril for 7 days, showed increased cough response. Ten microgram/kg FR190997, a non-peptide agonist of the bradykinin B2 receptor, also increased the cough response. Noscapine at 0.5, 1 and 2 mg/kg was able to reverse the effects of ACEI and FR190997. Naloxone, a specific opioid receptor inhibitor, did not block the antitussive effects of noscapine in enalapril or FR190997 treated guinea pigs. This antitussive effect of noscapine is not mediated via the mu, kappa or delta opioid receptors. It is therefore possible that noscapine exerts its antitussive action by interfering with the bradykinin cough mediation.

Abstract
Cytotoxic free radicals and release of several neurotransmitters such as bradykinin contribute to the pathogenesis of hypoxic-ischemic brain damage. We have studied the efficacy of noscapine, an opium alkaloid and a bradykinin antagonist, in reducing post-hypoxic-ischemic damage in developing brain of 7-d-old rat pups. Hypoxic-ischemic injury to the right cerebral hemisphere was produced by legation of the right common carotid artery followed by 3 h of hypoxia with 8% oxygen. Thirty to 45 min before hypoxia the rat pups received noscapine (dose = 0.5-2 mg/kg) or saline. Pups were scarified at 24 h post recovery for the assessment of cerebral damage by histological methods. Our results showed that noscapine was an effective agent in reducing the extent of brain injury after hypoxic-ischemic insult to neonatal rats. Therefore, it is concluded that noscapine may be a useful drug in the managements of patients after stroke.

Abstract
The clinically available opioids have different physicochemical properties, resulting in differences in clinical profile with regard to potency, onset, and duration of activity. However, they all have comparable side-effects after acute systemic application. Several approaches can be used to overcome these side-effects. The following approaches, with special emphasis on the perioperative use of the opioids, are discussed: (1) the use of alternative routes of administration, such as via the spine (epidurally and intrathecally); (2) optimization of opioid delivery by means of slow-release preparations, chronic infusions with indwelling catheters, and transdermal delivery systems; (3) use of additional agents to potentiate the analgesic properties of the opioids so that the dose of opioid can be reduced; and (4) searching for new analgesics on the basis of knowledge of the pain-transmission system and the different opioid receptors with their functional interactions.

Abstract
Our laboratory has previously shown that intracerebroventricular (i.c.v.) administration of beta-endorphin suppresses brain and liver ornithine decarboxylase activity (ODC; a growth regulatory enzyme) in preweanling rats. This investigation examined, in 6-day-old rats, the relative participation of brain mu-, delta- and epsilon-opioid receptors in beta-endorphin's ODC effects, by comparing tissue ODC responses to beta-endorphin given alone i.c.v. and in the presence of D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP; mu-opioid receptor antagonist), N,N-diallyl-Tyr-Aib-Aib-Phe-Leu-OH (ICI-174,864; delta-opioid receptor antagonist) or beta-endorphin-(1-27) (epsilon-opioid receptor antagonist). Administration of 0.5 microgram of beta-endorphin alone significantly decreased brain and liver ODC activity 4 h after injection, and the effect was completely blocked by coinjection of CTOP (0.075 micrograms) but not by ICI-174,864 (0.75 or 3.75 micrograms) or beta-endorphin-(1-27) (3.75 or 7.5 micrograms). The blockade of endogenous opioid:opioid receptor interactions by either CTOP (at doses > 0.075 microgram) or ICI-174,864 alone was accompanied by increased levels of basal ODC activity. The results obtained demonstrate that i.c.v. beta-endorphin downregulates ODC expression in central as well as in peripheral tissues by interacting with brain mu-opioid receptors, but not with delta- or epsilon-opioid receptors or mu/delta-opioid receptor complexes. Also, they indicate that endogenous opioid systems have a tonic inhibitory influence on ODC activity which is mediated, at least in part, by mu- and delta-opioid receptors.

Abstract
To evaluate the effect of inhaled diuretics, furosemide and amiloride, on cough induced by acid inhalation challenge in asthmatic children, a double-blind, randomized, placebo-controlled study was conducted. On separate days, 12 asthmatic children (10.3 +/- 0.7 [SEM] years) underwent acetic acid (AD) inhalation challenge after inhalation of furosemide (10 mg/m2 of body) amiloride (0.3 mg/m2 of body), or placebo (0.9% saline solution). Bronchoconstriction was not observed after administration of furosemide and amiloride. Both inhaled furosemide and amiloride exerted a protective effect against AA-induced cough in asthmatic children (p < 0.01 and p < 0.05, respectively), while there was little correlation between the individual protective potency of furosemide and amiloride against AA-induced cough (rs = 0.344, p = 0.255). These results demonstrate that both furosemide and amiloride can attenuate AA-induced cough, although, this protective effect of inhaled diuretics may not necessarily be dependent on Na(+)-K(+)-Cl- cotransporter or Na+ channel in airway epithelial cells.

Abstract
The effects of 7-benzylidenenaltrexone (BNTX), a selective delta 1-opioid receptor antagonist, and naltriben, a selective delta 2-opioid receptor antagonist, on the capsaicin-induced cough reflex were studied in mice. I.p. administration of BNTX in doses from 0.1 to 3.0 mg/kg reduced the number of coughs dose dependently. The antitussive effect of BNTX was antagonized by [D-Pen2,5]enkephalin (DPDPE), a selective delta 1-opioid receptor agonist, while [D-Ala2]deltorphin II, a selective delta 2-opioid receptor agonist, had no effect on the antitussive effect of BNTX. Pretreatment with nor-binaltorphimine, a selective kappa-opioid receptor antagonist, had no significant effect on the antitussive effect of BNTX. I.p. administration of naltriben, in doses of 1 and 3 mg/kg, also significantly decreased the number of coughs. Although the antitussive effect of naltriben was antagonized by nor-binaltorphimine, the antitussive effect of naltriben was not attenuated by either DPDPE or [D-Ala2]deltorphin II. The antitussive effects of neither BNTX nor naltriben were antagonized by beta-funaltrexamine, a selective mu-opioid receptor antagonist. Thus, it seems likely that the delta 1-opioid receptor antagonism may be involved in the antitussive effect of delta-opioid receptor antagonists.

Abstract
We examined the effects of rimcazole, a specific antagonist of sigma sites, on the antitussive effects of dextromethorphan and noscapine in mice. Intraperitoneal injection of rimcazole, in doses from 1 to 10 mg/kg, significantly and dose dependently antagonized the cough depressant effect of N,N'-di(orthotolyl)guanidine (DTG), a sigma ligand. The cough depressant effects of dextromethorphan (3 mg/kg i.p.) and noscapine (10 mg/kg i.p.) were also significantly and dose dependently reduced by pretreatment with rimcazole. However, rimcazole (10 mg/kg i.p.) did not have a significant effect on the antitussive effect of morphine (3 mg/kg i.p.). Furthermore, rimcazole by itself (10 and 30 mg/kg i.p.) had no significant effect on the number of coughs. These results suggest that sigma sites may be involved in the antitussive mechanism of centrally acting non-narcotic antitussive drugs.
